Degree of Threat: B : Moderately threatened throughout its range, communities provide natural resources that when exploited alter the composition and structure of the community over the long-term, but are apparently recoverable
Comments: The species as a whole is not seriously threatened, but the typical subspecies may be secure mostly where it is not native. The monaach appears to be doing well or even increasing in may places, but not in its core North American range. The native eastern North American populations are in trouble at their overwintering grounds. Overwintering habitats in Mexico are primarily in a few hectares each and have been under pressure from logging, agricultural and urban development. California based populations are declining more dues to problems in the breeding areas. Climate change is emerging as a current, rather than an expected, threat in Mexico, California, and Texas at least. There was some improvement in the eastern, as well as western, USA in 2010 so at least populations can still respond quickly to temporarily good conditions. Regardless of what happens in North America this species is at virtually no risk of global extinction in the forseeable future.
