Aside from environmental factors, present day genetic diversity. Lack of diversity = higher chance of extinction, high levels of diversity = higher chance of survival.
A catastrophic drop in population is the prime factor. This of necessity always precedes extinction. If a species has suffered such a decline you look first for environmental factors as a cause. If there has been no dramatic change in the environment ex disruption or flooding of habitat or changes of weather patterns, then look for pollution, then disease, then excess predation or competition, and lastly a similar decline in another species on which the species under study is dependent. If none of the above then it is just possible that such declines are part of a natural cycle. However this should never be assumed until the aforesaid possibilities have been eliminated.
