(Tracy Rittenhouse\/UConn Photo)<\/figcaption><\/figure>\n<p>The results were a little surprising. Most existing research about American black bears\u00a0indicates they prefer rural areas, and it\u2019s the amount of forest in those regions that determines the bear population density. But that literature is generated largely in western states like Colorado and Wyoming. This new information shows that Connecticut bears \u2013 and likely bears throughout the more heavily populated Northeast \u2013 are different. They are adjusting to living in a habitat shared with humans.<\/p>\n<p>American black bears see Connecticut as one big continuous forest with human housing scattered around in it, says Rittenhouse. While some towns may be home to more bears than others, any area where the forest-housing mix matches that exurban ratio should be considered habitat or future habitat for bears.<\/p>\n<blockquote>\n  <p>With low-density housing, we are actually creating a habitat that bears are using. <cite> &#8212 Tracy Rittenhouse<\/cite><\/p>\n<\/blockquote>\n<p>\u201cBears are opportunistic,\u201d Rittenhouse says. \u201cIf there is a place where they can find cover and that area is also close to a nice easy food source like a backyard bird feeder, they are very content to stay there.\u201d<\/p>\n<p>Looking at the study results, the vast majority of Connecticut is bear habitat, she says.<\/p>\n<p>\u201cThe bear population is expanding, essentially moving south and east from the north and west,\u201d Rittenhouse says. \u201cPeople generally think that there are enough people along the coast that the bear population won\u2019t expand that far, but our models indicate there is enough forest for the bear population to extend all the way to the coast.\u201d<\/p>\n<p>UConn\u2019s Center for Land Use Education and Research (CLEAR) has created an interactive <a href=\"http:\/\/clear3.uconn.edu\/viewers\/bears\/\">website<\/a> that summarizes the findings in this latest bear study. The site allows individuals to see the number of bear sightings in their town; the number of bears detected in the current study; and where Connecticut\u2019s bears may be headed.<\/p>\n<p>DEEP\u2019s wildlife experts plan to use the data to better track and manage the state\u2019s growing black bear population. The data will also help local town managers anticipate areas of possible bear habitat, and thereby allow them to plan future development and alert residents accordingly.<\/p>\n<p>\u201cThis study provided an independent, science-based population estimate that will be valuable in black bear management decisions,\u201d says Paul Rego, a DEEP wildlife biologist and a member of the research team.<\/p>\n<figure id=\"attachment_123083\" aria-describedby=\"caption-attachment-123083\" style=\"width: 400px\" class=\"wp-caption alignright\"><a href=\"https:\/\/today.uconn.edu\/wp-content\/uploads\/2017\/03\/howtocatchha.jpg\"><img decoding=\"async\" class=\"wp-image-123083 img-responsive lazyload\" data-src=\"https:\/\/today.uconn.edu\/wp-content\/uploads\/2017\/03\/howtocatchha-1024x682.jpg\" alt=\"Black bear hair sample on a barbed wire fence.

The region encompassed an area from the New York state line east to the Connecticut River, north to Massachusetts, and south to upper New Haven and Fairfield counties. The sampling area provided a full range of habitats from rural (less than six houses per square kilometer) to suburban settings (50 to 750 homes per square kilometer).<\/p>\n<p>The researchers collected hair samples once a week at 150 locations.
