 Establishing select native plants on Hawaii's highway right-of-ways.  This collection  of videos, reports and slide show images provides details on roadside site preparation for establishing native Hawaiian plants and establishment protocols for 3 native species:  Pili grass, Tropical Fimbry (Mau akiaki) and Seashore Dropseed (Akiaki).  These media were produced as the final deliverables for a HDOT contract titled: Native Grass Hydroseed Development (Project No. HWY-L_2005-06) completed in August 2012

 As demand for native Hawaiian Plants increases, it becomes important to develop seed production sites that have irrigation water, easy access and close to workers that maintain these plantings and harvest seeds.  The Hawaii Department of Transportation-Highway Division provided funding to develop seed production protocol for native Hawaiian plants on the highway-rights-of-way.  Four grass species were selected for adaption to dry lowlands, a climatic zone common to most of the roadways in the Hawaiian islands.  Content provided here provided as final deliverables for HDOT contract titled: Development Large Scale Seed Production and Roadside Establishment Protocols for Four Native Hawaiian Groundcovers (Task Agreement: 2011-2r) completed May 2015.

Seed production protocol was developed for 5 species of native Hawaiian plants.  Species selection for this project was based on characteristics that include; drought tolerance (thrives in less than 20 inches annual rainfall), can contribute to erosion control, are prolific seeders, produces seed with good viability and vigorous seed germination, can sever as pollinator habitat/food source and lend themselves to mechanical seed collection and planting.
