Montane Forest
The Mountain Pine Ridge Reforestation ProjectBackgroundBy 2000, the pine trees in the Mountain Pine Ridge Forest Preserve in Belize were heavily attacked by the Southern Pine Bark Beetle (Dendroctomus frontalis). The beetle did so much damage that the natural restoration of the pine forest was practically unattainable due to a lack of seed resources and continuing fires. The alternative is to abandon management and allow a pine savannah to develop. This paper compares the carbon sequestion potentional for a pine forest and a pine savannah in this region.

Face the Future: EcuadorBackgroundDue to high population levels and a constant reliance on natural resources for livelihoods, the Andes region in Ecuador has lost an estimated +90% of its primary forest. Since 1993, Face the Future and the Ecuadorian Ministry of the Environment have worked together to reforest this region. Goals & MethodThe objective of the project was to work towards reforesting the region through plantings. Farmers preferred species that grew well and had economic value, such as plant pines and eucalyptus. Native species were also planted, particularly within reserve areas. Open access copy available |
Multiple-Purposes Reforestation on Degraded Lands in Longyang, ChinBackgroundThe following is a project design document submitted to the UNFCCC in 2008 for a project to restore and preserve degraded forests in Longyang, Yunnan, P.R. China. The project will be headed by the Longyang Forestry Farm in cooperation with local farmers. Open access copy available |
Impact of Pine Plantations on Soils and Vegetation in the Ecuadorian High AndesbackgroundIn the Ecuadorian Andes, pine plantations of different ages and management strategies were evaluated for soils and vegetation against natural forest and grazed grasslands. These plantations were situated on volcanic soils. Open access copy available |
Overcoming Ecological Barriers to Tropical Lower Montane Forest Succession on Anthropogenic Grasslands: Synthesis and Future ProspectsBackgroundThis review attempts to address the difficulty in restoring grasslands to secondary tropical forest through reforestation. Proposed strategies are discussed for future recruitment methods for woody vegetation. Research Goals & MethodsThis study examines work conducted in Knuckles Forest Reserve (KFR) in the lower montane tropical rainforest and grasslands of Sri Lanka.

Seed rain under tree islands planted to restore degraded lands in a tropical agricultural landscapeBackgroundPlanting native tree seedlings is the predominant restoration strategy for accelerating forest succession on degraded lands. However, planting tree “islands” is less costly and labor intensive than establishing larger plantations and simulates the nucleation process of succession. Tree islands can attract seed dispersers to gradually spread restoration patterns from the islands. Restoration design can be informed by assessing the effect of potential planting arrangements on seed dispersal by birds and bats and determining the influence of surrounding forest cover.

Increasing Drought Sensitivity and Decline of Atlas Cedar (Cedrus atlantica) in the Moroccan Middle Atlas ForestsbackgroundSince the 1980s, severe droughts have influenced Atlas cedar mortality in Morocco. This study looked at relative contributions of tree characteristics and stand structure on the increment-growth and decline of Atlas cedar trees (Cedrus atlantica) in stands affected by past logging and heavy grazing.

The Cultural Context of Forest Degradation in Adjacent Purépechan Communities, Michoacán, MexicoBackgroundThis study aims to understand the relationship between cultural and ecological drivers contributing to change in forest land use patterns by comparing two adjacent indigenous communities in the volcanic plateau region of Michoacán, Mexico. The study suggests that both cultural and ecological processes must be studied together to best understand the cultural causes of forest change and accurately assess ecological consequences.

Rio Bogota - Fundacion al verde vivoThis project attempts to restore riparian forest along the headwaters of the Rio Bogota, upstream of the city of Bogota. Since 2003, the Fundacion al verde vivo has worked with volunteers to plant trees along the riparian corridor. Many areas along the riverbanks were previously used for cattle pasture, leather tanneries, or other small constructions. Local laws require that certain distances of riparian buffer are maintained as forest, but these regulations are rarely enforced. Plantings are conducted in rows with 1-2 meter spacing. Alnus plantings from 2005 form a canopy, and mid-successional species of oak, Spanish cedar, and other highland Andean trees are planted in gaps and in the understory.

Reserva Encenillo, Fundacion Natura, ColombiaThis reserve is located in high montane forest of the Colombia Andes, designed to protect the locally important forest tree Weinmanniatomentosa (Encenillo in Spanish). The total size of the reserve is 135 ha of forest, and serves as a forest corridor in a matrix of pasture, potato, and remnant forest landscape. Approximately 2-3 ha of degraded pasture were planted with Alnus acuminata in 2007. Alnus is planted in rows with approximately 3 meter spacing. Trees average mean annual increment is 1.35 cm at breast height, which is an average growth for the region; however, many trees had multiple stems, so total biomass is even larger.
