Structure And Floristic Composition Of Flood Plain Forests In The Peruvian Amazon: I. Overstorey, Gustav Nebel, Lars Peter Kvist, Jerome K. Vanclay, Henning Christensen, Luis Freitas, Juan Ruiz
Professor Jerome K Vanclay
Three Peruvian flood plain forests adjacent to the Ucayali river were sampled using nine 1 ha permanent sample plots in which stems exceeding 10 cm DBH were identified and measured. These plots were measured four times during 1993–1997. Three plots were established in each of the three forest types high restinga, low restinga, and tahuampa, characterised in part by an annual inundation of one, two and four months per year, respectively. Stem density varied from 446 to 601 per hectare, and the basal area ranged between 20 and 29 m2/ha. A total of 321 species were recorded in the nine …
Indicator Groups And Faunal Richness, Jerome K. Vanclay
Indicator Groups And Faunal Richness, Jerome K. Vanclay
Professor Jerome K Vanclay
Species richness is a popular indicator of ecosystem vitality, but is difficult to assess. Many natural resource managers seek an efficient bioindicator, but the link between candidate indicators and the richness of other taxononic groups remains elusive. A series of faunal surveys in the Mbalmayo Forest Reserve in Cameroon suggest that it may be possible to devise faunal bioindicators. The species richness of birds, of butterflies and of termites is significantly correlated with total faunal richness across eight species groups, suggesting that these groups may have potential as bioindicators, alone or in combination. Although expensive, further research is warranted because …
The Effectiveness Of Parks, Jerome K. Vanclay
The Effectiveness Of Parks, Jerome K. Vanclay
Professor Jerome K Vanclay
Bruner et al. examined the effectiveness of parks in the tropics, drawing on survey data to support their contention that parks 1) have been effective; 2) need more support; and 3) should remain a central component of conservation strategies. Their conclusions remain equivocal...
Deforestation In The Tropics: Reconciling Disparities In Estimates For India, Shaily Menon, Kamaljit S. Bawa
Deforestation In The Tropics: Reconciling Disparities In Estimates For India, Shaily Menon, Kamaljit S. Bawa
Shaily Menon
Here we examine recent disparate estimates of deforestation obtained for India. We discuss the sources of disparity and the implications of inaccurate estimates and suggest ways in which future attempts at estimating deforestation might reconcile the disparity. Despite the importance of deforestation and its consequences, no attempt has been made to reconcile the different estimates obtained for India.
