Locating SPB Spots from Ground Level
To find newly detected spots, use a map and compass, if necessary, to arrive at the general area indicated by the aerial survey team. Once there, look for a group of yellow- or red- topped pines (fig. 1). Spots that cannot be found after a reasonable search should be rechecked during the next aerial survey flight. The aerial crew may be able to correct errors in plotting or to pinpoint landmarks guiding you to the spot.
