That was the scene this morning near 37th and Lander (map). We stopped by after a call from city arborist Nolan Rundquist, who thought some passersby might be interested in why the trees were coming down: He says six big trees there had to go because of Dutch Elm disease — three were dead; the other three were dying and in danger of infecting others if not taken down. (We published a city warning about this disease, with some explanatory details, last August.) Rundquist told us a crew had a two-day window open during work being done for City Light, so they got busy in this neighborhood, at no cost to the homeowners. He added that some Bridging the Gap money might be available to replant in the neighborhood as soon as next spring.
