Helping Forests to Help Themselves—Accelerating Natural RegenerationbackgroundThis chapter walks through the basic techniques of accelerated (or assisted) natural regeneration (ANR), describing when it is appropriate, when it should be combined with other techniques, how to increase the seed rain, and areas of needed research.

Catalyzing native forest regeneration on degraded tropical landsbackgroundForest clearing, forest degradation, and the deterioration of land productivity due to inappropriate management is a major problem in the tropics. While traditionally, restoration of forest lands abandoned from human use has relied on natural forest regeneration, this paper explores the potential of plantations to catalyze forest regeneration in the tropics.

Forest Regeneration in a Chronosequence of Tropical Abandoned Pastures: Implications for Restoration EcologyBackgroundDuring the mid‐1900s, most of the island of Puerto Rico was deforested, but a shift in the economy from agriculture to small industry beginning in the 1950s resulted in the abandonment of agricultural lands and recovery of secondary forest. This research examines the natural regeneration patterns on these abandoned agricultural lands in four different regions of Puerto Rico. Available with subscription or purchase |
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.

Native Trees and Shrubs for the Productive Rehabilitation of Tropical Cattleranching LandsbackgroundThe authors of this study examined strategies to improve cattle ranching in Colombia and Mexico through the use of intensive silvopastoral systems. Silvopastoral systems transform extensive cattle ranching with intensively managed systems with high densities of trees and shrubs to improve yields and environmental impacts.

Release from Root Competition Promotes Tree Seedling Survival and Growth Following Transplantation into Human-Induced Grasslands in Sri LankabackgroundThis study evaluates the growth and survival of four native tree species planted as seedlings in grasslands situated in previously abandoned tea plantations. Research Goals & MethodsEach seedling underwent one of eight different treatments based the various combinations of: with or without root competition, shoot competition, and vertebrate herbivory. Seedlings that died within the first month were replaced. Growth and survival was evaluated at 18 and 28 months. Available with subscription or purchase |
Effects of fire on the recruitment of rain forest vegetation beneath Pinus caribaea plantations, Sri LankaBackgroundGroundstory fires burn forest understories and can impact advance regeneration, contributing to conversion of forests to fire-sustained grasslands or fernlands. While plantations of fire-tolerant trees have been successfully established on these sites, managing fire in the newly developing understory remains an issue of concern.
