Within the last nine months, hundreds of young trees in Golden Gate Park have been destroyed by an unknown person or group of vandals, and now a reward of $1,000 is being offered by the San Francisco Forest Alliance to anyone who can provide any information regarding these completely unnecessary crimes against nature.

According to San Francisco Recreation and Parks Department spokeswoman Connie Chan, more than 200 trees have suffered damage since September – with the most recent vandalism taking place in May.

The harmed trees were located in the western end of the park, and left to fend for themselves. Removal has become the only solution, as damage to treetops heightens a tree’s exposure to disease and rot. This part of Golden Gate Park is currently undergoing reforestation, and is marked to alert the public.

The damaged young trees were around 3 to 5 years old, and have a price tag of $250 each. Within the nine-month period of vandalism, the department has estimated the rising financial consequences adding up to $50,000 in damage, which does not include the time and effort it will take the staff to cultivate and support the vegetation. This is not the only instance where trees have been destroyed – Chan revealed that the department plants about 1,000 trees each year in the park, and around 20 to 30 trees suffer vandalism.
