Diversity and Conservation of Orchids Along the Ecological Tourism Route of Lum-Nam Nan and Klongtron National Park, Uttaradit

Abstract

Taxonomic survey of Thai wild orchids was performed at along the ecological tourism route of Lum-Nam Nan National Park and
Klongtron National Park and to conserve orchids by culturing onto a suitable synthetic medium composed of local materials. A survey
of orchids along the area of five meters around the ecological tourism route in a distance of about 21 kilometers was made from
December 2005 to February 2009. The taxa of orchids found in this National Park were terrestrial, epiphytic and lithophytic orchids.
They belonged to 5 subfamilies, 25 genera and 68 species and could be classified into Cypripedioideae 1 genus 1 species, Neottioideae 1 genus 1 species, Orchidioideae 1 genus 2 species, Epidendroideae 11 genera 49 species and Vandoideae 10 genera 15 species. They were grown at 1,100-1,400 meters above mean sea level. The length of stems and the number of shoots of D. formosum Roxb.ex Lindl. grown in the formula 3 medium (0.15%(w/v) fertilizer 21-21-21, 0.15% (v/v) vitamin B complex, 7.5% (w/v) Banana puree and adjust pH 5 by 15% (v/v) Pineapple juice). Experiments were statistically significant difference which it was higher than others treatments including Vaccine and Went. The conservation of 7 orchids were performed by bringing three years old grown orchids from seeds culturing back along the ecological tourism route of the National Park by pilot tourists and community organizing in the Park.
