Hudson River National Estuarine Research Reserve

L1 1 Engineered (hard)Engineered or constructed to stabilize or provide access, usually

vertical and without natural vegetated features

Nature 2 Soft Engineered (restored) Shore stabilized using plant materials or methods intended to improve

habitat

3 Natural Non engineered shore consisting of natural material or fill material, or

bedrock

L2 1 Revetment Non-vertical engineered shoreline

2 Gabion Rock held in place by wire mesh enclosure

3 Cribbing Rock held in place by timber frames

Structure 4 Bulkhead Solid vertical wall at river's edge, may be backfilled with a variety of

materials

5 Graminoid or broadleaf

vegetation

Broadleaf or graminoid, non-woody vegetation extending from intertidal

area to high tide line

6 Woody vegetation Brush, scrub or shrub, trees

7 Unvegetated No rooted vegetation

8 Woody debris Dominated by large woody debris

9 Other None apply, requires explanation in comments field
