Isolated Trees and Grass Removal Improve Performance of Transplanted Trema micrantha (L.) Blume (Ulmaceae) Saplings in Tropical PasturesbackgroundThis research evaluates the survival and growth of saplings of Trema micrantha when transplanted into recently abandoned pastureland in southeast Mexico. Trema micrantha is a pioneer species native to Mexico with ecological and physiological properties that would make it viable for planting in open fields. Research Goals & MethodsSaplings were planted in 2004 and evaluated every three months for the following year. Available with subscription or purchase |
Ecological Considerations for Using Dipterocarps for Restoration of Lowland Rainforest in Southeast AsiabackgroundIn this article, the authors present ecological factors that should be considered when engaging in dipterocarp forest restoration in Southeast Asia. Because many dipterocarps are insect-pollinated, have poor seed dispersal, have low density of reproductive adults, and have recalcitrant seeds, planting of nursery-reared tree seedlings could increase the ability of dipterocarp forests to regenerate.

Reforestation of Abandoned Pastures: Seed Ecology of Native Species and Production of Indigenous Plant MaterialbackgroundThis book chapter provides important considerations for sustainable native species reforestation efforts. The authors suggest that although using native species is more prevalent than ever before, there has been little attention to the provenance of the trees used and the genetic diversity within species.

Seed germination of Loxopterygium guasango, a threatened tree of coastal Northwestern South AmericabackgroundLoxopterygium guasango is a tree native to Ecuador with threatened status as of 1993, despite its durable wood, history of timber use, and potential use in reforestation. This study reports on seed germination, a potential cause of its low regeneration rates. Open access copy available |

Barriers to Forest Regeneration of Deforested and Abandoned Land in PanamaBackgroundThis article presents research findings on the effect of four limiting factors on tree regeneration: competition with the exotic grass Saccharum spontanaeum, seed dispersal limitation, fire, and soil nutrient deficiency. Research Goals & MethodsTreatments included prescribed grass cutting and burning, as well as the placement of plots at different distances from adjacent forest. Open access copy available |
Postdispersal Seed Fate of Tropical Montane Trees in an Agricultural Landscape, Southern Costa RicabackgroundThis study seeks to understand postdispersal seed fate in Montane Costa Rica in order to better identify factors driving forest regeneration. Available with subscription or purchase |
Propagating Framework Trees to Restore Seasonally Dry Tropical Forest in Northern ThailandbackgroundOne issue of concern in native species reforestation is the lack of information on propagation and nursery practices of native seeds and seedlings. Research Goals & MethodsThis research presents data on the germination and performance of ten native species that were formerly classified as possible "framework" species to be used in reforestation in northern Thailand.

Direct Seeding to Restore Tropical Mature-Forest Species in Areas of Slash-and-Burn AgriculturebackgroundDirect seeding of three mature-forest species into areas of slash-and-burn agriculture was conducted to evaluate the germination and establishment of these species. Research Goals & MethodsDifferent fallow times were evaluated, less than 5 years, 8-15 years, and greater than 50 years. Germination, survival, and growth for 1-2 years was evaluated for 1800 seeds planted per species (200 on each of three replicate sites per forest age). Open access copy available |
