Assisted Natural Regeneration
Direct Seeding of Late-Successional Trees to Restore Tropical Montane ForestbackgroundThis study measures seed germination, seedling establishment, survival, growth and foliar nutrient content of five late-successional tree species which were directly seeded into three different habitats representing different stages of succession in tropical montane Costa Rica.The study also compares the costs of direct seeding with locally collected seeds with planting nursery-raised seedlings.

The Effect of a Teak (Tectona grandis) Plantation on the Establishment of Native Species in an Abandoned Pasture in Costa RicabackgroundThis study compares native tree species recruitment in the understory of a 10-year-old teak plantation in premontane wet forest in Costa Rica to the native tree species recruitment on nearby abandoned agricultural land.

Barriers to Lowland Tropical Forest Restoration in the Sierra Nevada de Santa Marta, ColombiaBackgroundThis article examines the major barriers to forest restoration in the abandoned pastureland surrounding three forest fragments in the Rio Rancheria watershed of the Sierra Nevada de Santa Marta in Colombia. These barriers include: seed source, seed predation, competition from grasses, microclimate, soil quality, and fire. Available with subscription or purchase |
Attempting Restoration of Wet Tropical Forests in Costa RicaBackgroundThis article describes a reforestation effort of the Tropical Forestry Initiative using mixed stands of native species to recover abandoned pastureland in the tropical wet forest of Costa Rica.

Reasons for reforestation success and failure with three mangrove species in ColombiaBackgroundThis study examines the mortality and growth rates of the propagules, seedlings and saplings of three native mangrove species (A. germinans, L. racemosa, and R. mangle) in order to determine the ecological factors that influence tree growth and survival in deforested mangroves with restored hydrologic conditions on the Caribbean coast of Colombia.

Releasing Rain Forest Succession: A Case Study in the Dicranopteris linearis Fernlands of Sri LankabackgroundThis study evaluates the effectiveness of different site treatments for controlling the invasive fern Dicranopteris linearis which has arrested forest succession in areas of the Sinharaja Man and Biosphere (MAB) reserve in lowland Sri Lanka. The fernlands, which had existed in the reserve for 10-20 years before this study, are favored by forest clearance for swidden agriculture and periodic fires.

Role of Legumes in Release of Successionally Arrested Grasslands inthe Central Hills of Sri LankaBackgroundMany cleared and abandoned forest areas have changed to successionally arrested grasslands, shrublands, or fernlands maintained by frequent fires and high herbivore populations. Many studies have shown that herbaceous legumes can protect soil surfaces, retain soil moisture, improve soil fertility, and retard ground fires. This study evaluates whether some of these species can satisfactorily establish in these arrested grassland areas to aid in the trajectory towards reforestation.

Evaluation of Andean Alder as a Catalyst for the Recovery of Tropical Cloud Forests in ColombiabackgroundThis study compares the species composition and structural diversity of 30-year-old alder plantations with adjacent, naturally regenerated forests of the same age. The study seeks to determine if alder plantations are an appropriate catalyst for forest regeneration for conserving biological diversity and to determine if the differences between the two forest types are maintained over time.
