Extensive study has been made by FORRU, local forestry staff and students of Wailailak University of the trees of the lowland forest in the remaining range of Gurney’s Pitta in southern Thailand, including the identity of species and their flowering and fruiting phenologies. Over 180 species of tree have been identified and reference and voucher collections made of leaves and seeds. Phenology trails have been established and over 200 trees individually labelled.

seed extractionDetailed measurements of sapling growth rates have been made in the tree nursery to identify potential framework species for forest restoration, and field visits have established the identity of trees capable of regenerating in deforested areas. Three different forest restoration methods have been trialled and closely monitored at experimental plots; accelerated natural regeneration, replanting with framework species and direct seeding. All three show potential for wider forest restoration. A technical guide to forest restoration methods in the area has been produced.

Moreover, a local school curriculum “Gurney’s Pitta and Nature” was developed mainly by BCST and its partners. The curriculum aims to i) establish systematically basic learning about Gurney’s Pitta, ii) promote this subject at higher levels of education, iii) promote Gurney’s Pitta as a flagship species for conservation and iv) raise awareness of local people on Gurney’s Pitta conservation.
