80 Threars ro rhe Boelen's pyrhon (by Mark O 'Shea) Threats ro the Boelen's pyrh on (by Ma rk O 'Shea) 81 Threats to the Boelen's python (by MARK O'SHEA) T he threars to snakes in general, and pyrh ons in particular, are many and far ranging. Run over on roads, bush-knifed in garden s, hunred for meat or skins, killed out of prejudice or because of rnisraken identiry, subjecred ro lose of habitar through road­ building, slash and burn, rnining, forestry o r orher activiries, all faeror s rhar can con­ rribute the demise of a species, eirher locally or cornpl erely. Being proteered by laws, inrernarional, nation al, provincial 0 1' local , does not always pr evenr this problem. Mainl and New G uinea (Papua New Guinea, and rhe Papua and Wes t Papua Provinces ofIndonesia) po ssesses an impressive artay of pyrhon species amounting ro 13 species, wirh add itional spe cies occurring in a rchipelagos ro north, eas r, west and sou rhwesr, M ost of these pythons are eirher lowland coastal spec ies (Antaresia rnacu­ losa, Morelia spilota, Leiopython albertisii, Liasisfitscus) or spec ies wich island-wide dis­ triburi ons (Morelia amethistinn, M .viridis, Apodora papuana). Only rhe Boelen's pyr ho n (M. boelenz) can be said tO dernonsrrare a truly montane distribution above 1000m, absenr from lowland, coastal habi tars.
