Regeneration after Hurricane Hugo woody species > 1m tall (9ha grid, El Verde) (Large 9Ha Grid)
Abstract:
Purpose is to document vegetation damage and recovery following Hurricane Hugo.
Methods:
All woody species >/m in lenght in 2x2 m plot (excluding vines but including palms) were tagged and heigth and basal diameter measured. (see detailed protocol)
| Variable | Definition |
|---|---|
| Transect-plot identifier | Sixty 2x2 m seedling and sapling plots; associated with appoximately every other grid pole and representative of habitat frequencies; topographic locations and aspect. Format: A#; whereA is in{A;...;K; B is in {1;...;11} Sixty 2x2 m seedling and sapling plots; associated with appoximately every other grid pole and representative of habitat frequencies; topographic locations and aspect. Format: A#; whereA is in{A;...;K; B is in {1;...;11} |
| Species Code | A six letter code consisting of the first three letters of the genus and the first threee letters of the species A six letter code consisting of the first three letters of the genus and the first threee letters of the species |
| Tag Identifier | All woody species greater than 10 cm in height in the 1/2 X 2 mm subplot (excluding vines but including palms) tagged with orange flagging tape at the stem base. The seedling number sequence in each plot begins with 1 and goes as high as 1000. A palm is included if the leaflets reach 10 cm or more in height. An aluminum tag is added if the plant reaches 1 m in height. All woody species greater than 10 cm in height in the 1/2 X 2 mm subplot (excluding vines but including palms) tagged with orange flagging tape at the stem base. The seedling number sequence in each plot begins with 1 and goes as high as 1000. A palm is included if the leaflets reach 10 cm or more in height. An aluminum tag is added if the plant reaches 1 m in height. |
| Starting Date | First day of measurements conducted in the survey (in mm/dd/yy) |
| Seedling Height | Measured along the longest stem axis in non-palms. For shrubs that branch at the base; each stem greater 1 m tall receives a separate tag; each bearing the same plant number but differentiated by the addition of a unique letter (eg. 42A; 42 B; and 42C). Palm height recorded as the height of the tallest palm leaflets/ the height of bifulcation of the newest leaf bases. A blank in this field could mean that the plant is dead; the tag was not found; the plot has no vegetation; among other reasons. |
| Seedling Basal Diameter (dbh) | Mesured with calipers above any basal swelling. Switch to measure dbh when the plant grows 1 cm dbh. The first time dbh is measured; both basal diameter and dbh are recorded and stem is painted just bellow the dbh measurement point. A blank in this field could mean that the plant is dead; the tag was not found; the plot has no vegetation; among other reasons. |
| greater than 1m tall or Comment | count of individuals taller than 1 meter or researcher comment count of individuals taller than 1 meter or researcher comment |
