Dr. Luke J Pen (1960-2002) was a biologist and environmental scientist in South Western Australia. He researched and wrote about rivers and their biology and management. He died in 2002.
A memorial walk path on the Kalgan River commemorates his efforts and work to raise interest and knowledge in local rivers.
In 2008 a memorial scholarship in his name was created to support students of riverine environments in their research.
The Luke Pen Walk trail, located along the Kalgan River in the Albany Region, is a beautiful meandering walk trail, closely following the River. It offers a lovely mix of vegetation from large marri trees and conifers to farming pastures. Gorgeous views are present all the way along the trail.
This easy, well-formed nine kilometre takes approximately four hours to complete and commences at a well marked trail head on East Bank Road which runs off Nanarup Road. The walk provides constantly changing views of the river, along with a mixture of vineyards, green pastures with grazing cattle and eucalypt bushland. A shady walk for a hot day with opportunities to see the abundant wildlife that inhabits the river environment including pelicans, ducks and cormorants. While thornbills and both the Splendid and Red-winged Fairy-wrens can be seen in bush beside the river
