    Submitted by Northwest Trek Wildlife Park

    Eagle Passage isn’t just a forever home for rescued, injured bald eagles, or an immersive experience that inspires visitors with a conservation success story. Now, the unique habitat at Northwest Trek Wildlife Park has also been nationally recognized with top honors in the 2021 Exhibit Award category from the Association of Zoos & Aquariums.

    The award was presented online at the AZA Virtual Annual Conference on Wednesday, September 22.


    “Receiving this award is a high honor for Northwest Trek,” said Alan Varsik, director of Northwest Trek and Point Defiance Zoo & Aquarium. “Our visitors know how special Northwest Trek is, and it’s wonderful to have national recognition of the work we do. Eagle Passage is the result of our staff’s creativity and commitment to conservation, and the generous support of the Northwest Trek Foundation. This award recognizes that on a national level.”

    Eagle Passage opened to the public on August 3, 2019 as both a way to tell the bald eagle conservation story and as a home for rescued bald eagles injured in the wild. Enclosed with high airy netting, it utilizes many existing old-growth Douglas firs, with cables and mesh attached to the forest giants via a unique, bolt-free block-and-collar system that allows the trees free growth. A walkway through the center allows visitors to see majestic bald eagles close-up while giving the birds – all of whom have some degree of long-term wing injury – a safe passage between habitat sections.

    In addition, Northwest Trek operations staff created safe perches for the injured eagles using 100-year-old dead tree snags repurposed from where they had fallen in other areas of the park. Cheveyo, an eagle with a completely amputated wing, was given her own exclusive area with low perches and branches covered with anti-slip material to help her balance.

    To complete the experience for visitors, interactive displays tell the timeline story of how this iconic American species was saved from extinction by community action, as well as giving children a chance to “measure their wings” against a life-size graphic and climb inside a life-size concrete “nest.” Northwest native plantings, including 30-year-old sword ferns salvaged from construction sites, fill out both the habitat and the bigger ecological story.

    “My goal was to make Eagle Passage look and feel like where you would find bald eagles in the wild – up at Mount Rainier or on the Olympic Peninsula,” said wildlife park horticulturist Jake Pool.

    Eagle Passage cost a total of $578,474, which was raised by the nonprofit Northwest Trek Foundation from community donations. Key donors are recognized with bronze “feathers” on a low outside wall which surrounds a majestic bronze eagle statue by local artist Ed Kroupa.


    Native to North America and once plentiful across the United States, bald eagles were close to extinction in the Lower 48 states by the middle of the 20th century. The Endangered Species Act and other laws, such as a ban on the pesticide DDT, afforded them the ability to safely reproduce. The species is no longer endangered and is more than a national symbol; it is an example of how people working together can help protect wild animals and wild places.

    “Eagle Passage was designed to tell the recovery story of the bald eagle, reinforce our vital conservation mission and, most importantly, offer a message of hope to our guests and community about what we can do if we all care together,” added Varsik. “This award recognizes Northwest Trek’s cultural relevance, as well as our commitment to animal welfare.”

    The Eagle Passage habitat can be found in the main walking area of Northwest Trek, every day that the wildlife park is open. For more information, see the website.

    Welcome To CPC: Zoo New England

    Based on CPC Application

    Our network is growing, and with it grows our ability to save rare and endangered plants from extinction. Zoo New England (ZNE), located in Boston, Massachusetts, has a mission “to inspire people to protect and sustain the natural world for future generations by creating fun and engaging experiences that integrate wildlife and conservation programs, research, and education.” To that end, ZNE has been developing new organizational practices, weaving conservation into their onsite visitor experiences, and spearheading plant conservation projects to advocate for plants and biodiversity. These efforts made ZNE an excellent candidate for the CPC network, and the CPC Board of Trustees voted to approve their admission to the network in February 2021.

    In recent years, ZNE has placed strategic focus on honing their expertise in plant conservation to equally emphasize both plant and wildlife conservation in their work and onsite experiences. They have led small-scale reintroductions of a rare plant species in the Metro Boston area, the state-listed species, New England blazing star (Liatris novae-angliae), and they have worked with regulatory agencies to monitor populations of threatened Britton’s violet (Viola brittoniana) and the related Viola pectinata. ZNE’s robust plant collection – a highlight of their onsite visitor experience – includes pollinator plants in their butterfly exhibit, an organic garden, and a rain garden. To strategically expand existing plant collections, ZNE recruited horticulturists who collaborate with conservation staff in developing curated plant collections that reflect the geographic regions their animal collections are endemic to and also educate visitors about the role of plants in an animal’s ecosystem. Additionally, their team is developing new collections of native plants, succulents, carnivorous plants, and more.

    On an broad scale, ZNE has partnered with Dr. Bryan Connolly of Eastern Connecticut State University to conserve several species of rare Solanum native to the Caribbean. Utilizing ZNE greenhouses, the team has established captive populations of Solanum conocarpum from the U.S. Virgin Islands and Solanum ensifolium from Puerto Rico. Both species are critically endangered, with Solanum ensifolium believed to be nearly extinct in the wild. ZNE staff members have traveled to St. John, U.S. Virgin Islands, to assist with local reintroduction projects for Solanum conocarpum. ZNE hopes to eventually assist with reintroduction projects of two additional critically endangered Virgin Islands species, Erythrina eggersii and Eugenia earhardtii.

    As they continue in this crucial work, Zoo New England is eager to connect and collaborate with other Participating Institutions and to contribute to our collective efforts to Save Plants. Their team’s dedication to plant conservation and educating the public on the critical importance of biodiversity for all life on Earth makes them an exciting addition to the CPC network.

    Association of Zoological Horticulture

    2020-2021 Commitment to Plant Conservation

    Zoo horticulture involves more than enhancing the landscape for its resident animal populations as evidenced by the thousands of dollars used to protect and conserve the natural environment within our zoos and around the world.

    One of the core values of the Association of Zoological Horticulture (AZH) is conservation of rare plants and plant diversity.  This commitment to plant conservation through the AZH Plant Conservation Grant program began in 1992 and has awarded over $475,000 to projects spanning the country and the globe.

    AZH plant conservation grants encourage plant conservation activities and partnerships within and between AZH members, member zoos and member zoo partners.  Grant monies are provided through the Disney Conservation Fund (DCF), AZH member donations, and auction proceeds from annual conferences. AZH Plant Conservation Grants are awarded for both in-situ and ex-situ plant conservation work.

    Congratulations to the recipients of the 2020-2021 AZH Plant Conservation grant program!

    Halloween may be over, but common fungal diseases on tropical plants ensure that spooky season never ends in our interior exhibits. According to the Ohio State University fact sheet on the topic, fungal diseases wreak more havoc on plants than any other group of plant pest or pathogen. Estimates hover around 85% of plant diseases are caused by fungal agents. The spores and hyphae of these mysterious, understudied organisms are lurking in your water, soil and air, waiting to strike like the masked psycho in a horror movie.

    The very lack of what we understand about the Kingdom Fungi can make management difficult, however. They obtain nutrients by sending thread-like filaments throughout their food sources – you, me, a loaf of bread, your favorite plants, your jack o’lantern. They often hang around dead and decaying things (spooooky!) but not always. Sometimes they are straight-up evil parasites of living things. But, of course, evil is in the eye of the beholder – in this case, the beholder is the zoo horticulturist attempting to protect their tropical collections from the undead fungal hordes. Nevertheless, we should never forget the beneficial fungi that collaborate in vast mycorrhizal support systems for plant communities, as well as the yeasts that make sourdough bread and beer possible.

    But we are here today to discuss the villains! Below are some of the common symptoms of fungal infections in interior plantscapes:

    Leaf spots – Leaf spots are indicative of several different fungal species. Look for roughly circular tan/ reddish brown spots, concentric rings and small black fruiting bodies. If infection progresses, lesions may join together, killing off the growing tip or spread to branches of plants.

    Powdery mildew – Powdery mildew is not just one but several fungal species. What starts as powdery spots on upper leaf surface can join together to cover the entire leaf. Powdery mildew is often found in temperate, humid climate conditions - temperatures above 86 do not support powdery mildew.

    Stem canker – This infection is similar to an abscess- dark and mushy spots on stem. If an infection gets this far, the plant is usually not salvageable.

    Black sooty mold – This fungus looks as grimy as a Victorian street urchin. Black sooty mold grows on the honeydew exudate of aphids, scale, and other sap-suckers. That high sugar content encourages the growth of black sooty mold. If the mold gets heavy enough, it can shade out the plant and stunt its growth. The horticulturist’s first response is to take care of the insect pest, which removes the source of the problem.

    If fungal infections were like a horror movie, they would be like “The Thing”, starting off with small, seemingly innocuous symptoms but slowly infiltrating the plant completely and consuming it from the inside out. But unlike “The Thing”, the wise horticulturist does not need to blow up an entire Antarctic field station to contain the damage. Prevention and speedy diagnosis, as always, are going to be the most effective way to keep your plants healthy. Keep in mind that spores can live a long time and be carried by air currents, water, soil, tools and clothing, so our mantra for fungi should be “CONSTANT VIGILANCE” (shout-out to Mad-Eye Moody!).

    • Include fungal symptoms in scouting regimen
    • Check new plants for symptoms before installation
    • Sanitize tools and containers regularly
    • Eliminate cracks/ drafts if you suspect diseases are coming in from outer environment
    • If fungal diseases are a significant and ongoing issue in your exhibit, consider resistant plant varieties
    • May need lab analysis to pinpoint exact pathogen – most symptoms can be caused by wide array of fungal species

    The next best way to manage fungal infections is to focus on plant health care and adjusting conditions to be better for plants, but worse for fungi. In the horror movie realm, this would be analogous to if you never build a summer camp, you are less likely to get a masked murderer hanging around.

    • Reduce overall humidity
    • Water early in the day to allow plant surfaces to dry
    • Water to avoid wetness on surface of leaves, reduce overhead watering – dry leaves are less supportive of fungi. At Butterfly Pavilion, we often syringe our tropical exhibit for pest management, but we’ve gotten more focused over the years, so that we aren’t indiscriminately wetting leaf surfaces.
    • Increase air circulation through strategic pruning and thinning.
    • Remove debris from the ground regularly.
    • Follow a balanced fertility program to avoid too much or too little of key plant nutrients
    • Avoid wounding or stressing plant material as much as possible.

    If cultural methods are not effective, you may want to consider the ultimate in physical methods – removing the infected plant entirely from the exhibit before it can be a source of new infections. Fortunately, you’ll have better luck with plants than in most horror movie franchises; those monsters just keep returning and returning!

    Chemical controls can used to protect new tissue, but keep in mind that nothing can be done about the old infected tissue. Chemical fungicides, just like any chemical tool, require caution. Different fungicides are effective against different species of fungus, so checking the label is key. Fungicides can be irritating to skin, eyes and respiratory system, while chronic exposure may lead to negative health effects on the nervous system. Also, runoff and contamination, if it reaches the outside world, can negatively impact aquatic ecosystems and other organisms. For example, copper sulfate has been shown to have a negative effect on bees. Now that’s the real horror story!

    Honoring an accomplished person whose passion for life reflects ours.

    All too often in everyday life as horticulturists we experience the philosophical mindset of people who view plants as an inferior form of life to animals and/or the inability to appreciate the unique features or aesthetics of plants. We are focused on changing this mindset.

    In this regard, the Horticulture Team at the Jacksonville Zoo and Gardens would like to thank AZH for selecting us as a recipient of the 2020 Wendy Andrew Cultivation Grant. Despite being the “Covid-19” year, we were eager to share with the public our role in the Zoo and Garden dynamic.

    Choosing and planting a Southern live Oak (Quercus virginiana) was a conscious choice among our group because of the declining oaks in that area and the majesty of the mature tree.

    I personally started from seed (basically at no cost to the zoo during the pandemic) the Shasta Daisy (Chrysanthemum maximum) and Verbena speciosa 'Imagination' to use as colorful, bee and butterfly attracting undercover plantings!

    We eagerly await a recognition sign that’s design is currently in progress and I am personally excited to see the finished result. Once the sign is installed we will send an updated photo.

    A lot of time and hard work went into this project and I hope you agree that we accomplished the respect it deserves.

    Thank you for this opportunity and for your support,

    Robin Vancil

    Based on information from Hong Liu, Ph.D., Florida International University

    It was nearly 20 years ago that Hong Liu, Ph.D., was awarded the Catherine H. Beattie Fellowship. Working toward her Ph.D. at Florida International University (FIU), Hong used the fellowship funds to support her investigation of the impact of fire dynamics on a rare Florida keys endemic, narrowpod sensitive pea (Chamaecrista lineata var. keyensis). The fellowship, as well as her research, were important steps on her path to becoming a plant conservationist.

    The U.S. Fish and Wildlife Service (USFWS) supported Hong’s research on how rare plant species were being impacted by a fire management program designed to provide forage for the endangered Key deer, an endangered species. Though the pine rockland habitat supported many species adapted to fire and shallow limestone soils, Hong found that not all fires are created equal. In early summer, the sensitive pea sinks its resources into flowering and is most vulnerable. Fires occurring in this season prevented the plants from reproducing and were more likely to outright kill them. In contrast, late August fires allowed for the survival of plants and the recently matured seed. When the narrowpod sensitive pea was eventually listed through the Endangered Species Act, Hong’s dissertation (five years of field work and simulation modelling) became part of the backbone of the USFWS’s management plan on the refuge where she conducted her fieldwork.

    This fieldwork was central to the project’s success, and the Beattie funds helped get the fieldwork done. With freedom to use the funds as needed, Hong was able to buy needed field supplies and hire undergraduate assistants to help her collect data at her numerous plots. Perhaps more importantly, the Beattie Fellowship was a confidence boost for Hong: “To have my idea endorsed by a national plant conservation organization made me very proud.”

    In some ways, things have not changed much for Dr. Hong Liu since her Beattie Fellowship. She still conducts plant conservation research through FIU – only now as an associate professor in the Department of Earth and Environment and researcher in the FIU Institute of Environment. Her many research projects have focused on wild populations of endangered species. They include examining the impacts – and ways to reduce the impacts – of collecting pressure on wild orchids, the role of climate change on species, and the impact of biotic interactions on population persistence and expansion. In a current project, Hong is comparing populations of orchids that are rare in Florida (their northern distribution limit) to more populous communities of the same species in Cuba. She continues to work with pine rockland species, extending her studies to other rare plant species in this dwindling habitat type.

    But Hong hasn’t forgotten the plight of narrowpod sensitive pea. She is presently seeking support for a restoration project that will help the species become established on higher-elevation islands in the Keys, to enable the plant to survive rising sea levels. Her forward-thinking work continues to make a significant contribution to the long-term survival of endemic species in Florida.

    President of Cameroon Suspends Logging Concessions

    in Ebo Forest

    Conservationists Urge an Inclusive

    Land-use Planning Process to Determine Ebo’s Future

    Nearly three weeks after the government of Cameroon approved a forestry management unit that would destroy Ebo Forest in the country’s Littoral Region, on Aug. 11 President Paul Biya withdrew the decree establishing a logging concession and suspended the process for a second concession. Conservationists welcomed the news and are hopeful that the government will embark on an inclusive land-use planning process with local communities to determine the future of Ebo Forest.

    Ebo Forest is the ancestral land of more than 40 communities. The local Banen communities depend on Ebo Forest for food and traditional medicines. Any non-consensual development of the forest would heavily affect them. Before Cameroon’s independence in 1960, many communities lived in the forest, and their patriarchs and matriarchs are buried there.

    Chief Victor Yetina of Ndikbassogog and a representative of the Association Munen Retour aux Sources, and Ekwoge Abwe, manager of the San Diego Zoo Central Africa Program’s Ebo Forest Research Project, issued a joint statement following the news of the suspension of the logging concession: 

    “We welcome the suspension, for now, of logging plans in Ebo Forest, but are concerned that its fate remains unclear,” the statement read. “This decision must be the first step toward recognition of Banen’s rights and forest protection. We call on the government of Cameroon to adhere to its international commitments, and to promote participatory mapping and land-use planning with local communities. Land tenure reform must have, at its core, the full recognition of communities’ rights. We also call on international donors and NGOs to support these processes with technical expertise and resources, both in Ebo Forest and across the Congo Basin.”

    Ebo Forest is a hotspot for conservation research and discoveries. The forest provides critical habitat for many species of endangered primates, including gorillas, chimpanzees and red colobus monkeys. Researchers believe that the small population of gorillas in Ebo may be a new subspecies, because they are geographically distinct from other populations of western lowland and cross river gorillas. In 2005, researchers discovered that the tool-wielding Nigeria-Cameroon chimpanzees in Ebo Forest are culturally distinct from any other group of chimpanzees in Africa. They are the only chimpanzees to use tools to both fish for termites and crack hard-shelled nuts.

    The Cameroonian government had signed an international agreement to protect gorillas and their habitats on July 20, but two days later, it issued a decree establishing a logging concession in Ebo Forest. 

    “The president’s intervention to halt the imminent destruction of this unique forest is hugely welcome,” said Bethan Morgan, San Diego Zoo Global’s Central Africa Program head, who has been working to conserve the great apes of Ebo since she first observed gorillas there in 2002. “We hope that the international community will seize this opportunity to work with the government of Cameroon to make Ebo a showcase for long-term conservation, in harmony with very challenged communities. These communities have been responsible for the preservation of the treasures of Ebo to date, and an inclusive land-use planning process is now needed to fully share information, in order to make clear and calculated judgements about the future of the forest and its people.”

    Ebo Forest makes up half of the Yabassi Key Biodiversity Area, making it a site of global importance to the planet’s overall health and the persistence of biodiversity. It sequesters 35 million tons of carbon. Botanical survey efforts, supported by the Royal Botanic Gardens, Kew, with Herbier National Camerounais, have resulted in the discovery of 29 species new to science, and the area is known to contain 52 globally threatened species on the IUCN Red List of Threatened Species. Ebo is a proposed tropical Important Plant Area.

    “We are hugely happy with this positive news for Ebo,” said Martin Cheek, head of the team working on African Important Plant Areas at the Royal Botanic Gardens, Kew. “Not only is Ebo of incredible global importance for its documented plant diversity, but it is the most exciting forest in Cameroon in terms of the high numbers of new scientific discoveries of species still being found.”

    Cameroon’s Minister of Forestry signed two orders Feb. 4, proposing the classification of two forestry management units for timber extraction in Ebo Forest. The units would have destroyed the entire gorilla habitat and would have leveled the western part of the forest. The orders were posted publicly March 9, but that did not give the local communities living around Ebo sufficient time and opportunity to provide their input.

    “Ebo Forest is such an important site for primate conservation,” said Dirck Byler, great ape conservation director at Global Wildlife Conservation and vice chair of the International Union for Conservation of Nature’s (IUCN) Species Survival Commission’s (SSC) Primate Specialist Group. “With their habitat shrinking across Africa, it’s especially good news that Ebo can continue to provide a home for gorillas and chimpanzees. Hopefully it will be protected from any unsustainable development in the future."

    In April, more than 60 conservationists, including experts from the IUCN SSC Primate Specialist Group and Global Wildlife Conservation, signed a letter to Cameroon’s Prime Minister Joseph Ngute, asking that the plans for the logging concessions be put on hold and the government work with local communities to develop a sustainable land-use plan. They argued that adopting a more inclusive process would signal to Cameroon’s international partners during this critical year for biodiversity that the government intends to honor its commitments to reduce greenhouse gas emissions.

    2014 AZH Plant Conservation grant recipient Dr Murphy Westwood recently published results from study partially funded by AZH for "In situ and ex situ genetic diversity of the endangered Georgia oak, Quercus georgiana"

    Effectively conserving biodiversity with limited resources requires scientifically informed and efficient strategies. Guidance is particularly needed on how many living plants are necessary to conserve a threshold level of genetic diversity in ex situ collections. We investigated this question for 11 taxa across five genera. In this first study analysing and optimizing ex situ genetic diversity across multiple genera, we found that the percentage of extant genetic diversity currently conserved varies among taxa from 40% to 95%. Most taxa are well below genetic conservation targets. Resampling datasets showed that ideal collection sizes vary widely even within a genus: one taxon typically required at least 50% more individuals than another (though Quercus was an exception). Still, across taxa, the minimum collection size to achieve genetic conservation goals is within one order of magnitude. Current collections are also suboptimal: they could remain the same size yet capture twice the genetic diversity with an improved sampling design. We term this deficiency the ‘genetic conservation gap’. Lastly, we show that minimum collection sizes are influenced by collection priorities regarding the genetic diversity target. In summary, current collections are insufficient (not reaching targets) and suboptimal (not efficiently designed), and we show how improvements can be made.
