Fall 2000

Our progress in the breeding season just past was truly impressive, increasing the number of squares with all goals met by 71, to 217 or 45% of the total. Clearing thresholds is becoming a team effort, as the contributions of volunteers adopting squares, blockbuster weekends, incidental observations, and field assistants funded under our agreements with CalTrans, California State Parks, and the U.S. Forest Service complement each other. Congratulations to the participants listed below for their accomplishments, and thanks again to Pam Beare, Barbara Kus, Paul Jorgensen, and Kirsten Winter for arranging the funding that has enabled the extra effort to put many squares over the top.

In 46 more squares we have reached the interim goal of all criteria met with between 33 and 50% of the target number of species confirmed breeding.

Dark Gray >90% of target numbers of possibly breeding species have been recorded
>33% of target number has been confirmed

Many more squares are near the threshold: 27 are short only of the 25-hour criterion to reach their 50%-confirmed threshold, and 44 are short only of the 25-hour criterion to reach their 33%-confirmed threshold. In 389 (81%) squares at least 90% of the target number of possible species has been recorded, and in 445 (93%) at least 80% of this number has been recorded. We made so much progress over the spring and summer that I offer a map showing squares with fewer than 90% of the target number of possibly breeding species and fewer than 33% of the target number of confirmed breeding species as a guide if you're considering adopting another square.

If we can sustain this year's level of effort through the next and final breeding season of the project, we are sure to meet our ultimate goal of thorough coverage of the entire county.
