Cette carte illustre les aires de conservation prioritaires des prairies (ACPP) dans la r\u00e9gion des prairies centrales de l'Am\u00e9rique du Nord, un des \u00e9cosyst\u00e8mes les plus menac\u00e9s sur le continent et dans le monde.<\/p>\n

Les ACPP sont d\u00e9finies comme des aires qui rev\u00eatent une importance pour les trois pays en raison de leur valeur \u00e9cologique et du fait que la menace qui p\u00e8se sur elles exige un effort de conservation concert\u00e9 \u00e0 l'\u00e9chelle internationale.<\/p>\n

Les 55 ACPP ont \u00e9t\u00e9 d\u00e9sign\u00e9es par des sp\u00e9cialistes de la biodiversit\u00e9 \u00e0 la suite d'\u00e9tudes et d'un atelier organis\u00e9 entre autres par la CCE en 2004. On trouvera un compl\u00e9ment d'information sur le processus de s\u00e9lection des ACPP dans le document intitul\u00e9 North American Grasslands Priority Conservation Areas: Technical Report and Documentation<\/a><\/em>; la publication de la CCE intitul\u00e9e Prairies : Vers une strat\u00e9gie de conservation des prairies nord-am\u00e9ricaines<\/a><\/em> donne quant \u00e0 elle un aper\u00e7u de la situation dans les trois pays en ce qui concerne les prairies centrales de l'Am\u00e9rique du Nord et les probl\u00e8mes de conservation dans la r\u00e9gion.<\/p>\n

En 2010, les aires de conservation prioritaires des prairies (ACPP) ont \u00e9t\u00e9 actualis\u00e9es par le Rocky Mountain Bird Observatory (RMBO) en utilisant les donn\u00e9es cl\u00e9s suivantes : couches de donn\u00e9es nationales et internationales de l\u2019United States Geological Survey (USGS, Service g\u00e9ologique des \u00c9tats-Unis) relatives \u00e0 la couverture et \u00e0 l\u2019altitude; donn\u00e9es sur l\u2019habitat, les esp\u00e8ces, les aires prioritaires et la couverture terrestre provenant des \u00c9tats, des universit\u00e9s et des organisations non gouvernementales (ONG); donn\u00e9es brutes et produits d\u00e9riv\u00e9s des USGS Breeding Bird Surveys (BBS) et du Christmas Bird Count (CBC); donn\u00e9es sur le recensement des oiseaux et de la v\u00e9g\u00e9tation par le Rocky Mountain Bird Observatory (RMBO); donn\u00e9es de recensement des oiseaux du Service canadien de la faune (SCF) (par l\u2019entremise du portail de donn\u00e9es de l\u2019USGS) et donn\u00e9es recueillies par chaque chercheur. On trouvera des informations plus d\u00e9taill\u00e9es concernant la r\u00e9vision de chaque ACPP dans le rapport \u00c9valuation et r\u00e9vision des aires de conservation prioritaires des prairies d'Am\u00e9rique du Nord<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
