i = Thrcatenr_d,- A wildlife population is rated threatened when the indivirr oats constituting the population exist in such small numbers or arc sa restricted in their general distribution Lhat they may becrnne endangered, c = Common,- A population is considered common when its level is compatible with t}~e e>:isting }iabitat and is currently secure because its essential habitat is not t}trcatened by envirorrmental degradation, p Peripheral - A peripheral population is one which, because of being on the perimeter of its non;ial geographical range, occurs in low numhers. Altlrouglr not endangered or tlrrcatened in its population distribution as a whole, peripheral populations are subject to becoming endangered by relatit•cly minor changes in tlrci.r habitats. Such populations are seldom of substantial state interest unless habitat enlrancemen[ measures will result in t}reir status being upgraded, u = Undetermined or unl:no~.+n. Cn_lumn 4, Recommend for Select Species i.ist. Species recommended here arc candidate species for a select list which will be determined by an established review and selection procedure, Detailed irrtormation mill be duvelopcd for each species on the select list for the purpose of identifying significant wildlife habitats to be pro- tected under [he provisions of H.B. 1041, In addition [o indicating which species you recommend for inclusion on t-he select list, you should ran' these numerically, starring with irunber 1 for the species you consider most important, and continuing on to those you consider less important. The follo:~irrg criteria should be considered in detenniring candidate species for the select list: (1) General Distribution of the species should be well enough known that it can be r..appeel. (2) Biologi.ca7. features of the species' local distribution should be l:nosm or such info oration should be readily obtainable. Th^se biologic:'. features, which may not apply to all species and may be more important for some t}ian others, include [}ie followi.ng: production areas, prin- cipal fcedino areas, summer ranges, winter ranges, concer.[ration areas, shelter areas, water and mineral requirements, movement corridors, buffer zones an3 special Habitat needs. (3) Sp:.cies should har,•c: positi•:e economical, social, educational or ecolo- gical val~~es. (4) Species desi~at~d as an official state or fe'_erzl ar.i^al, i.e., bi;,::orn sheep, tar}: bunting aid bald eagle, should be included. (5) Species r~nich are unique in their Colorado distribution, i.e., found in only one or a few areas, should be included. (6) Include species on official federal or state list o: errdanE;er~~d sl~eci.~s. To assist you in this regard, a list of endangered species is a„ended to [he clicc}: list. v
