In August 2020 TRLP launched our Seed Grant Program. This initiative fosters collaborations with in-country conservation partners, providing modest but essential funding to bridge funding gaps or to enhance existing conservation activities. Individual activities that will have outsized positive impacts relative to the contribution are ideal.
Helping Cuba's coffee farmers transition to native species shade plants
Ten percent of Cuba's 1,735 native trees are threatened by extinction due to illegal logging, habitat degradation, biological invasions, and agriculture. Rainforest clearing has led to the destruction of habitat, as illegal logging and careless management of the region's extensive coffee plantations continues to threaten the survival of the remaining populations. TRLP’s grant to Planta!, an environmental NGO headquartered in Vancouver, British Columbia, Canada, allows it to upgrade its native plant nursery at the Topes de Collantes nature reserve park in the Guamuhaya Mountains of central Cuba. This region is one of the most species-rich on the island and a place of renowned natural beauty.
Topes de Collantes is home to the critically endangered Magnolia cubensis subsp. acunae, a plant with large fragrant white flowers and a wood of remarkable strength, occurring in fewer than 10 localities, none of which shows a healthy population structure. Most populations contain only 1 to 3 old individuals, and only one presents young trees (12 in total). No seedlings have been found.
Another endangered plant from the region, Podocarpus angustifolius, is a rare conifer known from only two populations, one represented by a single adult plant and the other by no more than 174 mature individuals. Both species grow between 700 and 950 m above sea level, the same elevation range and area occupied by Cuba’s montane rainforests.
During the last decade, Planta! teams have planted over 3,000 magnolia saplings and additional 1,660 Podocarpus in region’s protected areas, and to lesser extent, in coffee farms. The TRLP financial support will allow Planta! to increase the nursery production of these rare trees and to support landowners transitioning from non-native canopy trees typically found on coffee plantations to canopy trees of native species with locally sourced seeds. As Planta! helps to preserve and recover Cuban threatened tree populations, in partnership with local communities, the involvement of farmers in conservation is key to the long-term sustainability of these efforts. The Red List Project is proud to support this critical work.

Supporting seed collection and propagation of the threatened Maiapilo (Capparis sandwichiana)
Hawai’i is renowned for its biodiversity, particularly its native flora—almost 90% of its flora is found nowhere else in the world. These islands are also known as the “endangered species capital of the world,” with more than 100 plants species confirmed as extinct and another 200 species known only from populations of 50 or fewer individual remaining in the wild.*
The Red List Project is pleased to partner with the National Tropical Botanical Garden (NTBG) to help conserve Maiapilo (Capparis sandwichiana) on the island of Kaui’a. Maiapilo is a medium-sized shrub in the caper family (Capparaceae), most commonly found on cliffs, lava flows, emerged coral reefs and in rocky gulches of coastal areas of the Hawaiian archipelago. Its beautiful night-blooming white flowers are large and extremely fragrant flowers, opening after sunset and lasting only one night, withering just after sunrise.
Capparis sandwichiana is known from several of the Northwestern Hawaiian Islands and the eight main Hawaiian Islands. Although the total population numbers are in the thousands across its range, subpopulations and suitable habitat continue to decline rapidly. On Kauaʻi, the total number of mature individuals is only around 500 individuals in populations are threatened by habitat loss through coastal development and exotic species, sea level rise, and by predation by feral goats and rats.
Previous work on C. sandwichiana by NTBG staff included the mapping and tagging all individuals on Kauaʻi that could be accessed on foot, an effort that resulted in documenting 11 individuals at Polihale on the west side of Kauaʻi and 57 individuals in the Māhāʻulepū area of southeast Kauaʻi. Not surprisingly, no regeneration was observed and rat predation of immature fruits was ubiquitous.
This conservation project seeks to
• Obtain targeted conservation collections of seeds from wild individuals that have been mapped and tagged,
• Store a portion of seeds in NTBG’s Seed Bank and Laboratory,
• Propagate plants in NTBG’s Conservation and Horticulture Center nursery that are collected from different individuals and populations remaining on Kauaʻi to expand and enhance the living collection of plants in NTBG’s three gardens on Kauaʻi,
• Provide opportunities for research, including obtaining a scent profile of the extremely fragrant, night-blooming flowers, and
• Raise awareness of the importance of plant conservation through education and outreach.
This work fulfills the missions of both The Red List Project and the National Tropical Botanical Garden, supporting conservation work to help prevent the loss of genetic diversity. In the few remaining populations of this threatened plant species on Kauaʻi, expanding ex situ collections of stored seed and living collections of plants in multiple locations can be used for future in situ restoration work. Raising awareness about plant conservation in general and the importance of protecting the extremely threatened, coastal habitat on oceanic islands are two key outcomes of preventing the extinction of this lovely island rarity.

Supporting Magnolia conservation in the cloud forests of the Dominican Republic
The Dominican magnolia (Magnolia domingensis) is an IUCN “Critically Endangered” species that has been the conservation focus of Fundación Progressio for more than two decades, and is also the focus of a conservation action plan by the Red List Project partner Botanic Gardens Conservation International (BCGI). Once thought to be widespread on the island of Hispaniola, it is now considered extinct in Haiti, and restricted to only two populations in the cloud forests of the Dominican Republic, one in Loma Rodríguez and the other in Loma Barbacoa, Peravia province. Together these two geographic distribution extends across only six square kilometers of its original habitat.
This Red List Project Seed Grant is supporting Fundación Progressio's project to augment existing M. Domingensis populations that have been diminished in size, and to reintroduce this magnolia to habitat where it once occurred. Natural regeneration—mostly the result of fallen trees that resprout from the base—is extremely limited. Little to no seedling recruitment occurs.
Fundación Progressio has extensive knowledge and deep experience in the collection of seeds from natural populations as well as in the production of seedlings in a nursery setting. They have propagated approximately 800 plants that are held in the native plant nursery of the Ébano Verde Scientific Reserve (RCEV). This nursery stock is sufficient to establish a two hectare plantation as an initial step in reintroducing these magnolias to the cloud forest.
Fundación Progressio will do this magnolia outplanting in October 2020 to take advantage of favorable climatic conditions. In early 2021, two trips to collect additional seed will continue this conservation work—a trip to Loma Rodríguez in January and another in February to Loma Barbacoa.
In September 2021, a second habitat will be prepared for outplanting, where the Dominican magnolia will be eventually restored to protected wildlands. The magnolia saplings will be transported first by truck from the RCEV nursery to Loma Rodríguez. From there, the plants will travel, again by truck, to Valdesia, Peravia and on to the community of Laguna, Valdesia. The final transport to Loma Rodríguez will navigate the difficult terrain via horse and mule.
Advancing Community-based Conservation in Southwestern Madagascar
The arid landscape of southwestern Madagascar is home to an extraordinary floristic assemblage — the Malagasy spiny thicket. Endemism defines the ecoregion with almost the entire indigenous flora found nowhere else on earth. Tragically, this exceptional biodiversity is caught in the crosshairs of poverty and climate change. The remoteness of the region has hampered conservation efforts and left the local community extremely vulnerable to climate change impacts and exploitation of natural resources by external entities.
The Red List Project has provided a Seed Grant to the California Academy of Sciences (CAS), in support of their work to address mounting biodiversity loss in this region. In collaboration with University of Antananarivo (UofA), CAS botanists have initiated a long-term community-based conservation project. The heart of the project is a remnant of white-sand, spiny thicket adjacent to Lavavolo village. The pulse of the project is the community itself. The objective is to mobilize resources and empower the community to steward their natural heritage into the foreseeable future.
To this end, the long term goal is to implement a management plan encompassing sustainable use, restoration and inclusive land protection. The starting point for this project is a Comprehensive botanical assessment within white-sand habitat between Itampolo and Ankazoabo. TRLP funding will support an in-country partner conducting preliminary botanical assessment and ethnobotanical studies in the vicinity of the Lavavolo community. In addition, it will allow the team to engage in the following actions:
• Aggregation of botanical data (inventory, vegetation mapping, etc.) conducted within this region
• Introductory community and partner meetings
• Delimitation of property ownership and/or management units with the area
As is the case for any community-based conservation program, success will be contingent on realistic strategies for management of resources. This requires respect for near-term community needs along with incentivized long-term benefit.Both are integral to this project. Success is equally reliant on local stewardship, so capacity building is fundamental. Field activities will be conducted by Malagasy graduate students with mentorship from principal investigators from CAS and UofA. Local community members will also be trained and remunerated for field support. On a broader scale, community members will be key in formulation of a long-term plan for preservation of critical habitat in the vicinity of Lavavolo.
