Figure 4:  A small “research class” hydroseeder being used by Plant Materials Center staff in a Southcentral gravel pit plot.

Figure 5:  Totes of Arctophila fulva (arctic pendant grass), an emergent grass species, researched by the Plant Materials Center for potential value as a habitat enhancement species.  This was one of the few species used in transplanting trials.

Figure 7:  The same site on Shemya Island in September 1988.  

Figure 8:  An area selected for natural revegetation monitoring on Shemya Island. This road is being reclaimed with a locally excavated peat overlay that is allowed to develop a vegetation cover without assistance.

Figure 11: A landfill compacter being used to loosen and imprint the surface of an old gravel pit.

Figure 12:  The imprinted pattern on the surface of the gravel pit.  The pock marks trap moisture and seed.  The steel wheels of the compacter (sheep’s foot) on the hard surface loosen the soil, forming a more vegetation-friendly condition.

Figure 13:  The effect of natural revegetation after two years. Note the establishment of woody species.

Figure 14:  The same area after three years.

Figure 15:  An area being prepared for natural revegetation by using a ripper bar on a grader.  This is the final condition of the prepared surface.

Figure 19:  A sand quarry restoration project on Adak Island that relied on transplanted beach wildrye (Leymus mollis) sprigs and seeded grasses native to the area.  The photo shows one season’s growth.

Figure 20:  The same area after three growing seasons.

Figure 21:  A small surface disturbance on the Northwest Arctic coast.

Figure 27:  After two winters and another growing season the 1979 plot looks even more depleted in 1981.

Figure 28:  After initial evaluation it is necessary to increase the amount of seed in the inventory of those species selected for advance testing. This photograph is of one initial increase plot at the Plant Materials Center.

Figure 33:  ‘Alyeska’ polargrass (Arctagrostis latifolia) is one of the cultivars being produced by the PMC for use in revegetation. This was one of the early cultivars developed by the University of Alaska.

Figure 34:  ‘Kenai’ polargrass (also Arctagrostis latifolia) was developed for southern regions of Alaska.

Figure 35:  ‘Norcoast’ Bering hairgrass, Deschampsia beringensis, is an important revegetation species for coastal areas in Alaska. This cultivar was developed by the University of Alaska.

Figure 36:  ‘Nortran’ tufted hairgrass

Figure 37:  ‘Caiggluk’ Tilesius’ wormwood, Artemisia tilesii, is a cultivar developed by the PMC. This broadleaf has a wide range of adaptability throughout Alaska.

Figure 38:  ‘Nugget’ Kentucky bluegrass is no longer recommended for standard revegetation. Its use should be limited to landscaping projects in urban or residential areas. This field is a foundation seed production field at the PMC.  The other two cultivars of Kentucky bluegrass resemble ‘Nugget’.

Figure 39:  ‘Reeve’ beach wildrye was a 1991 release by the Alaska Plant Materials Center. This cultivar, unlike the native collection ‘Benson’ beach wildrye, was released for seed production.

Figure 40:  Adak Germplasm arctic bluegrass

Figure 41:  Viviplets of a viviparous arctic bluegrass plant are shown in this photograph.  Note the root development.  This root development occurred in less than 24 hours.

Figure 71: Broadcast seeding using shoulder-carried seeders works well on small areas and steep slopes where motorized equipment may have problems.

Figure 72: Drill seeders are specialized types of equipment that work best on level sites with fine soils.

Figure 73: Brillion seeders are forgiving and can be used on gravelly and rocky sites more reliably than other drill seeders.
