Walk through Time in the Highlands
Ecology & Evolution at Our Feet
Life has been on an immense journey through time, and it turns out that much of the evidence for that journey is all around us in the natural world. On this short hike we will look for the evidence that the plants, animals and even the rocks have changed over time, creating ever more complex ecological relationships and ever richer ecosystems. This walk offered a condensed version of a 5-day program on this subject that Dana taught last summer in the Methow Valley.
Dana Visalli, botanist and editor of “The Methow Naturalist,” led a guided hike along a hidden canyon connecting the Burge Mountain road and the Highlands Nordic Sno-Park near Havillah.
Lost Lake: Inside the Gem
This presentation on February 5th, 2016, outlined how OHA is preserving the Lost Lake wetland, making the site available to researchers, and teaching youth about the value and function of wetlands, using Lost Lake as an example. Delve with us here into the depths of this gem, and take a look at the array of botanical wonders that thrive at the Preserve…

Living with Fire

On Friday, May 1, 2015, Jason Llewellyn and Dale Swedberg co-presented about fire ecology and fire history, and shared our region’s story of fire management. Dale Swedberg provided an intro to fire history and fire ecology. Jason Llewellyn discussed what goes into a prescribed fire, from the decision to use fire as a tool, through the planning phase, to carrying out the plan and keeping fire where it is intended. Living in an ecosystem that has been dependent on fires for millennia, we can either tolerate wildfires or support prescribed burning, but it is impossible to have neither.
Stream Ecology 2015
“No bugs, no fish!”

Mark shares from a book that he co-authored about macroinvertebrates.
On Friday, March 6th, OHA’s Highland Wonders series welcomed back a highly popular speaker from last summer’s outdoor events: freshwater ecologist and emeritus professor Dr. Mark Oswood.
Stream Ecology 2014
On Saturday, July 19th, freshwater ecologist and emeritus professor Dr. Mark Oswood came to share his expertise in the Highland Wonders series. This event aimed to increase our community’s understanding of stream ecology, and how riparian zones and streams interact to support and affect populations of aquatic insects. Connections were made between populations of aquatic insects and what their presence indicates about water quality.
Wild Mushrooms and Fungi Ecology
The April 11th, 2014, Highland Wonders event on Wild Mushrooms and Fungi Ecology was dedicated to OHA volunteer Marge McCormick, who recently passed away after a battle with cancer. We appreciate everything Marge did to help further OHA’s work in the highlands, and she will be greatly missed.
Watershed Functioning, Plant Ecology, and Stream Processes
Two highly qualified stream experts lead one of OHA’s 2013 summertime Highland Wonders field trips, offering a unique opportunity to learn about our highland waterways.
Seeing the Forest Among the Trees
From the Panorama to the Patch: How do People Fit?
Renowned forest ecologist, Herb Hammond, kicked off the Summer 2013 Highland Wonders series with a unique perspective on Okanogan Highlands ecology. “Seeing the Forest Among the Trees,” featured a Friday evening presentation with a Saturday outdoor field trip the following day. This two-part approach provided the best of both venues for maximum learning and enjoyment.
