Pollen count count is by using a Burkard Trap, also known as the seven-day volumetric spore trap. This device works by facing towards the wind and drawing in air by using a pump. The pollen particles drawn in by the pump are then trapped by a sticky wax film that is attached to a rotating drum. The drum slowly rotates one turn over the course of seven days while collecting particles. The tape is removed after one week and cut into day-length sections. Pollen count Pollen count is the measurement of the number of grains of pollen in a cubic meter of
Compartmentalization of decay in trees compartmentalization. According to CODIT, when a tree is wounded cells undergo changes to form "walls" around the wound, slowing or preventing the spread of disease and decay to the rest of the tree. By increasing understanding of how trees respond to decay, CODIT has had many applications. For example, arborists are frequently called upon to analyze the danger posed to people or property by a damaged or decaying tree. By knowing how decay is likely to spread, such hazard tree analyses may be more accurate, thereby preventing unnecessary tree removal, property damage, or injury. For another example, in the production
