Estimating Pollen Contamination Inloblolly Pine Seed Orchards By Pollen Trapping

The construction of an inexpensive, easy-to-build pollen trap is described, which rotates to keep the trap oriented into the wind at all times. These traps have been deployed for several years, both within and surrounding four loblolly pine (Pinus taeda L.) seed orchards ranging in age from 7 to 25y. A comparison of pollen caught on both the orchard and background traps permits an estimate of how much pollen the orchard is producing relative to background. The resulting estimates of background contamination are very similar to those obtained with other methods.
