Objectives: Despite the substantial loss of natural forest in the Bosomkese Forest Reserve, little is known on the effects of the massive habitat loss and degradation on forest biota. The study therefore assessed the effects of anthropogenic activities on butterfly species composition and abundance in the Bosomkese Forest reserve in the Brong Ahafo region of Ghana. Methodology and Results: The ...

Forest canopy moisture content is an important factor in determining forest fire risk and forest fire behaviour. In Dargon 2 project, to develop a suitable regional early warning technique to predict forest fire risk, a Normal Difference Water Index (NDWI), which has been calculated by using the reflectance of SWIR and NIR band of HJ-1B IRS, has been used to retrieve forest canopy moisture cont...

A floristic and ecological study of bryophytes and macrolichens in different lowland rain forest types around Mabura Hill, Guyana, South America, yielded 170 species: 52 mosses, 82 liverworts and 36 macrolichens. Lejeuneaceae account for about 30% of the species and are the dominant cryptogamic family of the lowland rain forest. Special attention was paid to the flora of the forest canopy, by u...

The forest canopy harbors a diverse assemblage of plants of many different growth habits. The reproductive parts of tall trees, many epiphytes, and lianas may exist only in the upper canopy. Access to these upper regions is essential to identify canopy plants and to collect and document voucher specimens for a particular forest region. The majority of botanists, however, have relied on collecti...

Seventeen exclosures were built by the New Zealand Forest Service within Urewera forests over the period 1961-68 to exclude ungulates. Forest structure and species composition inside and outside these exclosures were compared in 1980-81. Some relatively shade tolerant species such as the fern Asplenium bulbiferum, the liane Ripogonum scandens, the sub-canopy shrubs Geniostoma ligustrifolium and...

The use of lidar and radar instruments to measure forest structure attributes such as height and biomass are being considered for future Earth Observation satellite missions. Large footprint lidar makes a direct measurement of the heights of scatterers in the illuminated footprint and can yield information about the vertical profile of the canopy. Synthetic Aperture Radar (SAR) is known to sens...

Canopy interception plays an important role in determining the amount of rainfall reaching the forest floor. During a rainfall event, water either penetrates the canopy falling directly to the understory of the forest floor, or is intercepted by the canopy. From there it can drip to the ground surface, flow down tree stems, or be held and evaporated. The portion that falls directly to the groun...
