This trip will look at various invasions along an elevation gradient from Kona (sea level), up the eastern flank of Mauna Kea (1800m), but focus on higher elevation areas that were cleared for pasture and have been actively restored. We will discuss plant invasion, restoration success and limitations, and the role of domestic grazing and feral ungulates. Our final destination, Hakalau National Wildlife Forest Reserve is also one of the best places to observe Hawaiian honeycreepers, some of which are endangered, so avian ecologists will be on hand to point out bird species.
Our first stop will be at Waikoloa Dry Forest preserve to look at expansive fountain grass (Pennisetum setaceum) invasions and remnant/restored dry forest. Dry forest habitats are some of the most threatened across the globe. Our route will then take us up Saddle Road towards Mauna Kea/Mauna Loa, pointing out prominent invasions along the way such as Leucaena leucocephala and Senecio madagascariensis. After a short stop at Pu‘u huluhulu to see views of Mauna Loa and Mauna Kea, we will take Mauna Kea Access Road to Mana Rd and stop to look at gorse (Ulex europaeus) invasions. We will spend most of the day at Hakalau Forest, stopping first to look at Acacia koa reforestation areas with persistent alien grass understory, discuss restoration trial and error and persistent problems. We will also hike (1-2 miles depending on preference) down into intact forest areas and look for endangered plants and birds. Please be aware that hiking is on gravel roads at 1800 meter elevation (6000ft) in wet/mesic forest, so be prepared for warm and sun in the lowland forest, and damp, cool conditions in the upland forest.
