Apparent Violations:
Two sets of vehicle tracks visible, one of which was a BLM official. The ATV track may have been an illegal entry.
Activity Comments:
The BLM recently used a Caterpillar to level the Snowy Plover nesting area and reduce European beach grass clumps. The usual ropes and signs were not yet in place.
Notable Wildlife:
There was a minimal amount of wrack high on the beach consisting mostly of bullkelp and some washed out beach grass. Birds observed were two Snowy Plovers, two mature Bald Eagles, a flock of Sanderlings and one lone gull. There were three or more Harbor Seals patrolling the outlet from Tenmile creek. They team up to feed on steelhead and salmonids entering or leaving the freshwater. They seem to be there year around and past counts found up to eleven present. Rodent and deer tracks on beach.
Dead Birds:
Fish & Invertebrates:
Kelp or Algae·Animal casings (e.g. crab, shrimp molt)·Ocean-based debris (from fishing boats, ship trash, etc.)·Shells·Wood pieces
New Development:
Dune Modification
Beachgrass removal and grading by the BLM for plover nesting area.
Natural Changes:
Erosion of vegetated foredune
What a great day for a beach walk. The only concern was who put the vehicle tracks on the non-vehicle beach leading up to Tenmile Creek? BLM employees use both ATVs and 4wd vehicles to monitor the nesting area. Occassional illegal entry also occurs. Other signs of human activity centered around the blading of the sandy nesting area of 6-10 acres between the ocean and the small estuary. Rodent and deer tracks were noted, and three Harbor Seals were actively patrolling the outlet for fresh fish. A pair of adult Bald Eagles were observed soaring over the outlet. Other bird life included a flock of Sanderlings, a pair of Snowy Plovers, and one lone gull. Parts of the sea wall were eroded back by wave action leaving vertical walls up to eight feet. Shells, animal casings, Bull Kelp, wood and ocean-based debris in driftline. Low human impact (0).
