Scientists knew about the smoke (they could see it) and how bad it was in specific areas.<\/p>\n
Where was the actual air quality when the animal was standing there?<\/p>\n
Why air-quality monitors often miss wildlife exposure<\/h2>\n
Most air-quality monitors are intended to provide safe air for humans.<\/p>\n
They are typically located close to townships and communities.<\/p>\n
Because monitoring stations are placed for people rather than wildlife, deer, elk, and bears often travel far beyond the nearest sensor.<\/p>\n
So, if you take a measurement taken miles from where the animal is standing, it probably won’t tell you what the animal<\/strong> breathed.<\/p>\n Instead of measuring exposure, scientists would often have to make estimates of exposure instead of direct measurement.<\/p>\n Scientists have been studying wildlife for years and are very good at following the animal\u2019s migration routes.<\/p>\n The data collected from GPS collars can demonstrate where the animal went and how they utilized the landscape.<\/p>\n One component was missing: with animals constantly on the move, researchers couldn’t tell how much smoke<\/strong> they inhaled along the way.<\/p>\n As time passed, the lack of knowledge concerning smoke exposure limitations hindered research that connected smoke exposure to either behavioral responses or physical health effects.<\/p>\n Researchers at Colorado State University<\/a> bypassed stationary air monitors to find a direct way to track animal smoke exposure.<\/p>\n To accomplish that goal, the scientists built a compact smoke-monitoring unit which they attached to existing wildlife-collaring systems that researchers were already using.<\/p>\n The device contained a small solar-powered unit that measured PM2.5 and recorded these measurements every thirty minutes.<\/p>\n Therefore, a portable smoke monitor was produced<\/strong> that followed the animal through its movement through the environment.<\/p>\n This portable smoke monitor allowed researchers to determine what ambient PM2.5 concentration existed at the exact point of observation by the animal.<\/p>\n While this technology measures local smoke concentrations, it does not yet show how animals react<\/strong> or how health is affected.<\/p>\n However, this technology does allow researchers to begin collecting data necessary to investigate both behavioral responses<\/a> and potential health effects due to wildfire smoke exposure.<\/p>\n Collecting data on exposure is an essential initial step before addressing subsequent impacts.<\/p>\n Collars for wildlife can generate enormous quantities of data.<\/p>\n Researchers can identify the route taken by the animals.<\/p>\n They can track how those routes change over time.<\/p>\n In many cases, researchers can correlate those observations to various<\/strong> environmental factors such as weather or habitat conditions.<\/p>\n With this new sensor, another layer can now be added to this picture of an individual animal’s movements in relation to those environmental factors.<\/p>\n The data generated by this new sensor can be compared with other data<\/a> already being collected from the same animal.<\/p>\n This will enable them to formulate hypotheses<\/strong> and test them rather than infer results based upon indirect evidence.<\/p>\n <\/p>\n As wildfires grow more frequent across western landscapes, researchers finally have a way to measure smoke<\/strong> directly from the animal’s perspective.<\/p>\n Future studies can build upon the measurements collected by the sensors.<\/p>\n Researchers may be able to identify patterns<\/a> that were previously difficult to detect.<\/p>\n The smoke itself may already be familiar.<\/p>\n The view from inside it is only now becoming clearer.<\/p>\n","protected":false},"excerpt":{"rendered":" Wildfires create so much smoke that it covers mountainsides and doesn’t stop at highways, towns, or park borders.
