A hammerdirt project

Page 2: Litter survey Nov 2015 - January 2016

2 The projectMontreux Clean Beach Project II (MCB-PII) removes and inventories macro-plas-tic pollution from the shoreline of Lake Léman.The data collected can be used to evaluate current litter mitigation strategies. MCB-PII is designed and inspired by the citizen science method.MCBPII is the second project initiated by hammerdirt. The results of MCBPI and the project plan can be found at our website www.hammerdirt.ch. The project plan de-scribes our methods, provides references and defines the deliverables for MCBPII.

DataThe data for each survey location is avail-able for download from our website, fol-low the “Kobotoolbox” link for the location in question. Once you have accessed the “toolbox” you can download the data, view the results on a map or view the results one by one, images are included.

AssociationAll the labor and resources for this project are furnished by hammerdirt association. We are always looking for serious, dedi-cated individuals that would like to fund, initiate or participate in projects of this type. For more information, visit our web-site.

FundingMCBPII is unfunded, all costs for the proj-ect have been assumed by Shannon and Roger Erismann, the founders of ham-merdirt. We would like to expand our operations to include more locations and more surveys. Individuals or groups inter-ested in funding this project or an expand-ed version should contact us directly.

4 Combined resultsTotal pieces found

Twenty-seven operations yielded 8’560 pieces (pcs) of trash for the period of No-vember 23, 2015 to January 27, 2016. Of that total 2’003 pcs were removed in one operation from “La plage de l’Arabie” in Vevey. This beach is not normally part of the project and is not included in the combined survey results that follow.

Variety of items foundThe variety of material found represents seventy-six “Marine Litter Watch “ (MLW) categories, an 8.6% increase from the last period. Cigarette butts, pieces of foam and pieces of plastic combine for 60% of the items found. Bottles/broken glass, snack food wrappers and cotton-swabs round up the top 6 items representing 72% of the trash found on these beaches.

Plastics and averagesPlastic in all forms represents 84% of all material found and fluctuates between 59% - 97% of the daily total. The moving average of daily totals reached it’s peak of 276 pcs on 10/12/2015 to finish at 252 pcs.

6 A comparison of key categories as a % of daily totalsWe compared the % daily totals of cigarette butts, foam, bits of plastic and cot-ton swabs across the three survey sites. We combined Montreux rive gauche with Montreux rive droite and “La plage du Pierrier” was added to the Baye de Clarens. Cigarette butts make up 25% of the items found across all sites, Montreux consitent-ly has the greatest amount of cigarette butts as a % daily total ranging between 10% and 60% for the period.

Cotton swabs as % of daily totalNov 2015 - Jan 2016

Vevey Clarens Montreux

The cyclical nature of the beach cast litter is evident and the relative quantities be-come more similar across the sites when cigarette butts are removed from the inven-tory results. This is espe cially evident for cotton swabs where the peaks and troughs appear to coincide.

Food related items as % of daily totalNov 2015 - Jan 2016

Veveyse Clarens Montreux

All food related categories were combined and compared as a % of daily totals. The chart is similar to that of cigarettes in two very important ways:1. Montreux has the highest percentage of this type of litter2. The graph is flatter, the period between peaks and troughs is longer

ConclusionsWhen cigarette butts are removed from the daily to-tals, the % quantities and occurrence of foam, cot-ton-swabs and plastic pieces are similar across all three sites. In the case of food related items, with a chart similar to cigarette butts, the elevated quantities at the Baye de Montreux may be a problem to that lo-cation. Given our experience and the results from the first project we expect this pattern to be confirmed as the surveillance continues.

RecommendationMontreux could benefit from a litter prevention pro-gram targetting the areas directly adjacent to the lake and La Baye. Specifically on the beaches themselves and in the shops and restaurants in the immediate area.A consolidated regional effort to reduce the amount of foam introduced in the environment is adivsable. Additional data collections, meteo & hydrologic data as well as increased cooperation from the communes would be useful to analyze in greater detail the fluctu-ations of material collected at each of the 3 sites.

²Maximum density of trash per meter²

Nov 2015 - Jan 2016

Plage de l’ArabieThe plage de l’Arabie is about 70 meters from the Veveyse. This site has never been surveyed before, and the prox-imity to our regular site seemed like an interesting opportunity to compare findings.At 76m² the Arabie is smaller than any of the four sites, stairs provide acces to the beach from the boardwalk. The to-tal inventory for the site was 2’003 pcs, representing 46 different MLW catego-ries.The density of trash present was obvi-ous when we arrived on site, in relative terms the Arabie presents a density 6 times greater than the maximum value of any other beach under surveillance. When compared to other studies, the Arabie had a greater density of trash than the average found on one kilome-ter of beach in England.

Four categories occupied 56% of the trash found on the beach:1. Candy wrappers2. Bits of plastic3. Plastic sheeting4. Plastic cupsForty-two other categories com-bine to make up the rest.

2’246 pieces of trash were removed in seven opera-tions from Montreux rive gauche(MRG). With a maxi-mum density of 4.24pcs per m², MRG has the highest density of the sites under regular surveillance.The precipitous drop in quantity of litter found on January 19, 2016 could be attributed to the results of our sustained efforts, cold weather, or wave events removing the material.Increased cooperation with the commune is needed to better analyze the fluctua-tions.

1’880 pcs of trash were removed in seven oper-ations from the Baye de Clarens. With a maximum density of 3.92pcs per m², The Baye de Clarens has the second highest densi-ty of the sites under regu-lar surveillance.The sharp increase for the last two weeks of January is attributed to wave ac-tion that deposited pre-viously submerged waste onto the beach.The weather data needed to verify this has yet to be disclosed.

69% of the items found can be attributed to 4 categories :1. Foam2. Plastic pieces3. Cigarettes4. Cotton swabsThe rest of the litter found (31%) is spread out among 60 other categories.
