Abstract
-
An ecological inventory was conducted in a forest fragment located within the boundaries of El Imposible National Park El Salvador. The area was selectively logged 21 years ago and an abandoned shade coffee plantation is also fund in the park. Three sites were chosen and 28 (20 x 50 m) permanent quadrats were established (site 1 = 10 quadrats, site 2 = 8 quadrats and site 3 = 10 quadrats). In this report, these sites are called El Ujushtal, La Fincona and La Montafiona. A total of 3800 trees were identified, marked, measured for height, diameter at breast height, and x,y coordinates. Voucher specimens were collected far those species not identified in the field. All vouchers have been deposited at La Laguna Botanical Garden, San Salvador. The corners of all plots were marked with cement markers for reference in future studies. Aluminum twos were used try mark all trees included its the inventory. Analyses were completed at the quadrat, site and at the entire area level. The number of species per site varied from 48 in site 1, 66 in site 2 and 37 in site 3, belonging to 39, 38, and 29 families respectfully. Approximately 174 of in estimated 400 tree species were inventoried in the entire park. Monte Carlo tests of complete spatial randomness (CSR) were done for all quadrats (28). The dominant species in site 1 is Brosimum alicastrum (Moraceae); site 2 is Alstonia longifolia (Apocynaceae) and for site 3 Rheedia edulis, (Clusiaceae). Two recent human disturbances are having negative effects on the tree diversity of the study sites: free-ranging horses and fuel wood collection. An ethnobotanical study of plant knowledge about Brosimum alicastrum (Moraceae) wars also included in this project. A questionnaire was designed to quantity the transmission of knowledge to adolescents in a rural and urban setting, significant difference was found between the two groups. Rural informants knew more abut ujushte than the urban interviewees did. Both groups indicated that their main source of knowledge abut Brosimum was their grandparents.
