“It wouldn’t be called research if we knew what we were doing.” -EinsteinIMG_7240Big thanks to Dr. O’Hirok and Patrick Costa for coming out to help pick spots along the beach that would give the most exciting results for profiling. Learning how to use the GPS was also helpful given the sand is forever moving.

SandCrabs and Micro Plastics/Fibers

As of Friday I was able to get 31 sand crabs dissected and 20 of them had ambient fibers in their stomach content or surrounding tissues.  That is approximately 64% of the sandcrabs so far have ambient fibers.  Since the data from the summer research institute shows that a high percentage of the beaches sampled also had fibers and micro plastics, I hypothesize I will continue to find microfibers in the sand crabs.

Over the weekend I was able to travel north to San Louis Obispo county and collect 35 more crabs from 3 different sites as well as sand samples to process.  Hopefully my contacts in Orange county, Santa Cruz and San Francisco will come thru with more sand crabs and sand samples as well.  I am hoping to get a wide geographic range in sampling to see what I find.

Once the collected crabs are dissected I plan to test a hypothesis that the sand crabs will ingest micro plastics by sequestering them into small jars with sea water and exposing them to plastic microbeads I have filtered out of a face soap product that will be on the “to be banned” list if legislation is passed.

Torrey pine

I am currently working on an application for a permit from the Torrey Pines State Reserve (TPSR), as well as collecting background references for my Capstone introduction.

Recon Success

Island Paintbrush
Island Paintbrush

This weekend on Santa Rosa Island, I did recon work for Water Canyon. This weekend was very productive, I now feel confident identifying the plant species in this watershed and a plan for future data collection has been established. This week the logistics of the project will be finalized and I will be ready to collect data on friday!

Getting the Ball Rolling

This weekend(9/27/15) was a good start to collecting data. With the help of some friends I accurately surveyed four out of the five of my survey sites. I have already surveyed these points but have honed in on my techniques with greater accuracy and ease. In addition to surveying, I also took a shore line track. Since the start of school I can visually see sections of the sand start to disappear. In general, the waves this weekend were small. Needless to say, there were still some fun waves to be caught. Some thoughts for improvement on my researching would be to buy more sunscreen and bring a big umbrella(the sun was strong this weekend). I also found it to be easier to make a straight line with the transect tape by walking backwards holding the compass. Overall successful weekend of collecting data. I would like to thank Andrew Shimizu and Lauren Zahn for coming out and helping me survey. Great success!

Non-Native Invasive Species on Santa Rosa Island

IMG_3569My capstone project will be focused on non-native invasive species on Santa Rosa Island. There are many invasive species on the island, most of which get dropped there as seeds from visitors shoes or gear and will often take root near Ports of Entry. These invasive species then compete with natives for space and nutrients to thrive, diminishing the natives populations greatly. I will work on creating a Plant Identification Chart for others to easily identify invasive species. I will also catalog plants using a GPS unit to map out a 20m zone around Ports of Entry as well as sample 500m transects along dirt roads and trails to see how much coverage invasive species are taking up. Ultimately the goal of this project will be to effectively map out the locations of these invasive species and create a management plan to potentially begin restoration. I hypothesize that invasive species will higher in coverage near Ports of Entry than Dirt Roads and Trails further inland.

Abstract

Water Canyon Vegetation

Abstract

This capstone project will take place in Water Canyon on Santa Rosa Island. Cattle and elk heavily grazed Santa Rosa Island for 150 years having severe impacts on the vegetation. The island has been going through recovery for 3 years after the last elk was removed in 2012. This study will look at the vegetation distribution throughout the watershed, primarily focusing on the riparian habitats and terraces. Surveys will be conducted to identify species within cross sections of the stream channel. Patterns of population niches will be identified. Further research will be conducted from literature to identify why certain species inhabit certain areas.

Vegetation distribution will be examined with regards to upstream/ downstream patterns, elevation, slope, and materials within the stream channel (boulders, rocks, soils, etc.). Additionally, Invasive species will be identified and examined to see the impacts on the native species. It is anticipated that biodiversity will decrease with an increase of invasive species. The study will compare the expected vegetation in Water Canyon with literature that focuses on vegetation in stream channels and significantly impacted areas. This project will be collecting baseline data that can be used in future research projects after the island has more time to recover or after any significant natural event.
