    My family loves conifers. We have over 500 different species planted at our house- most of them dwarf varieties. Unfortunately, the deer love them, too. To discourage browsing, we make our own deer repellent with old eggs, milk, dishwashing liquid, water, and chili powder.

    What's something you have learned since becoming involved with Wissahickon Trails? 
    When being on the trail, to not disrupt nature and leave logs that are not on the path alone. 

  • Bob Brockway

    I am a retired President/COO of a large independent soft drink company.

My children / grandchildren live in the area and my wife and I would like to help leave as much of this blessing to future generations. 

    What's one environmentally friendly practice that you have adopted and why?  
    Plastic bottles have a negative impact on our environment. As a board member of the Pepsi Cola Bottlers Association, we encouraged Pepsico to adopt environmentally responsible packaging which helped pressure our parent company to develop new biodegradable packaging enabling significantly reduced plastic disposition in our country's landfills. I will continue to advocate for innovations required to solve this important environmental issue. 

  • Suzanne Bush

    I am curious about the world--from the critters in our yard (there are lots of them!), to the ways geography has been destiny for people throughout the world. I'm a writer and an animal lover, and my husband and I are chronic travelers.

    What's one environmentally friendly practice that you have adopted and why?
    Composting! It's a great way to turn veggie scraps, coffee grounds and egg shells into fabulous fertilizer for the garden. 

    What's a practice you have changed since becoming involved with Wissahickon Trails? 
    My husband and I are much more intentional about what we plant and where, so we avoid planting species that are invasive; we look for plants that pollinators like and trees that are native. And, no chemicals on the lawn, on the weeds or in the garden!  

    Why did you join Wissahickon Trails' board?  
    I have been a volunteer at Wissahickon Trails for more than 20 years, and believe that open spaces and trails are amazing gifts. It has been a privilege to be part of the board.

    What's one environmentally friendly practice that you have adopted and why?
    Water conservation - to limit careless use of a valuable natural resource.

  • Harm Scherpbier

My wife, Titia, and I grew up in the Netherlands, moved to the US over 30 years ago, and now live in Fort Washington, PA. 

    What's one environmentally friendly practice that you have adopted and why?  
    I like to pretend that I don't have a car and do all my local trips by e-bike. It helps reduce my carbon footprint, and it's fun! 

    What's something you have learned since becoming involved with Wissahickon Trails? 
    On the trails, we often see a new bird or a plant and we use iNaturalist or Merlin to look up the names, and so we learn while we're hiking.  

  • Kristian Smith

    By day, I am a non-profit professional managing fundraising programs that grow and engage a committed constituency and government affairs efforts that mobilize the power of community support.

    What's one environmentally friendly practice that you have adopted and why?  
    As someone who lives along a tributary of the Wissahickon Watershed, I am continually learning better yard care strategies and gradually converting my landscaping to native plants. Not only is better for the birds and insects who live along the creek, it’s fun and great outdoor exercise!
