An island family donated the 18-acre Jack Island to the San Juan Preservation Trust in 2007. While the island is undeveloped and hosts a wide variety of wildlife, it also is home to a very thick undergrowth of invasive plants including English ivy (Hedera helix), English holly (Ilex aquifolium) and English laurel (Prunus laurocerasus). The Preservation Trust has relied on dedicated volunteers and crews from the Washington Conservation Corps (WCC) to systematically remove these plants to reduce the threat these invasives pose to our native flora. While we have made some significant progress, this eradication effort will need to continue for many years into the future.
