Seasonal Calendars

As the calendar flips from December to January signaling the beginning of a new year, Harney County residents look out toward the snowpack on the Steens and Blue Mountains searching for hope and clues for late spring water and wet meadow verdancy. April and May water levels tell the story of what is going to happen in the plant world for the rest of the year. In late March or early April, Wet Meadow plants wake up from their winter dormancy, providing critical and choice grasses, rushes and sedges for both birds and cows.

Wet meadows have the amazing ability to thrive with flooding in the spring, and still survive drought conditions after mid-summer. By the end of June, wet meadow plants have reached peak growth. As summer progresses and water levels recede, plants maximize their growth, putting out seed heads. By late summer, plant growth has slowed down preparing for winter dormancy. Wildlife and wet meadow land managers are constantly adapting their management goals and strategies to this variability. Learn more about winterspringsummer and fall in the Harney Basin.

The Seasonal Calendar Project was created to document the seasonal nature of the meadows. 2021 was the kickoff to a 6 -year effort to use drone photography and on the surface water sensors to document water presence and plant response throughout the year at 4 wet meadow sites in the basin. Drone photos were taken at each site in March, April, June, September 2021 and April 2022. The drone flies the exact same path on each flight, showing the greening, drying, and browning of each site through the seasons.

Documenting wetland plant community composition and habitat quality in response to varying water levels will provide the framework for development of water and vegetation management strategies and decision tools in anticipation of climate change predictions of earlier spring rains and less snow accumulation and summer water inputs.

The seasonal calendar products in conjunction with the Harney Basin Wet Meadow States and Transitions Model, wet meadow manager workshops and vegetation and bird surveys will help set a community wide basin vision and actions that conserve wet meadow habitats in perpetuity and in turn support flood irrigation, agricultural activities, health and survival of bird populations and the Harney Basin economy. These products will assist in understanding and adapting to changes in water levels and plant communities in response to climate change.
