Survey
Results at a Glance
They survey results for 2006 are now complete and and have been
added to the overall at-a-glance chart below:

Our 2006 cranefly survey was expanded to include Lake Samish, Lake
Whatcom watersheds and surrounding areas. The results have been
tabulated and show NO crane fly problems in need of control measures.
In our survey this year, we also searched for another potential
pest that has not yet been found in Washington State, the European
Chafer. The larval stage of this beetle is also a pest of turf grass,
eating roots just like crane fly larvae. Our volunteers surveyed
over 60 homeowners' lawns, and NO traces of these white grubs were
found either.
A warm thank you goes out to the Master Gardners and associated
volunteers that worked on the survey this year, as well as the homeowners
that enrolled to have their lawns surveyed.
Critical Levels for Action

Your Decision |
| 0 to 25 |
Do nothing; fertilize appropriately. May need
to treat if turf is young, not well established or with poor
root structure. |
| 25 to 50 |
If your lawn is vigorous and healthy, do nothing.
Decisions are based on the health of the turf, your personal
tolerance, location and use of the turf |
| 50 to 80 |
Treat crane fly problem. Look towards long-term
solutions, such as replacing problem areas with a turf
alternative species. |
