Latest On The Conservation Gateway

A well-managed and operational Conservation Gateway is in our future! Marketing, Conservation, and Science have partnered on a plan to rebuild the Gateway into the organization’s enterprise content management system (AEM), with a planned launch of a minimal viable product in late 2024.

Characterizing Drainage Flows that Result in Smoke Intrusions from Prescribed Burning: Rx Burning in the WUI of Bend, OR

Susan O’Neill, Miriam Rorig, Rick Graw and Roger Ottmar

Recording of a presentation at the May 2015 AMS Fire and Forest Meteorology Conference in Minneapolis, MN.

Excerpt from the abstract: “At night, the nocturnal inversion sets up, trapping emissions from the smoldering stages of fires, which can lead to smoke being transported along river drainages directly into towns. The complex terrain makes it particularly difficult to predict when smoke from fires, sometimes many tens of miles away, will be transported into smoke sensitive areas.”

Comments from Blane Heumann (TNC): Burning in Bend OR is burning in a “fish bowl” from a smoke perspective. I took away a couple bits to think about: smoke models do not currently do well at predicting smoke issues from overnight or extended smoldering consumption; and cool stuff using weather station data and typical burn prescription to calculate statistics on number and timing of available burn days (in terms of temp, RH and winds).​
