AIS NL Biofouling Species Fisheries and Oceans Canada's (DFO) National Marine Biofouling Monitoring Program conducts annual field surveys to monitor the introduction, establishment, spread, species richness, and relative abundance of native and some non-native species in Newfoundland and Labrador (NL) Region since 2006. Standardized monitoring protocols employed by DFO's NL, Maritimes, Gulf, and Quebec regions include biofouling collector plates deployed from May to October at georeferenced intertidal and shallow subtidal sites, including public docks, and public and private marinas and nautical clubs. Initially, (2006-2017), the collectors consisted of three 10 cm by 10 cm PVC plates deployed in a vertical array and spaced approximately 40 cm apart, with the shallowest plate suspended at least 1 m below the surface to sample subtidal and shallow intertidal species (McKenzie et al 2016a). Three replicate arrays were deployed at least 5 m apart per site. Since 2018, collector networks have been modified to improve statistical replication, including up to 10 individual collectors deployed per site at 1 m depth and at least 5 m apart (as above) from May to October. Since 2006, seven invasive biofouling organisms have been detected in Newfoundland and Labrador harbours, marinas and coastal areas.

Reference: Tunicates Vase tunicate (Ciona intestinalis) 2012 The Vase tunicate, is a high impact solitary invader and was first detected by DFO in 2012 on the Burin Peninsula at Ship Cove and Little Bay, Placentia Bay. Various mitigation measures (McKenzie et al. 2016b) contained this invasive tunicate to a small area for six years within Placentia Bay. First detected in Fortune Bay as an established population in 2019, increasing reports of the Vase tunicate have been made along the south coast of Newfoundland. The data provided here indicates the detections of this AIS in coastal NL. From 2018-2022, the Coastal Environmental Baseline Program provided additional support to enhance sampling efforts in Placentia Bay.

Aquatic invasive species (AIS) are non-native species that pose ecological and/or economic threats to Canada's coastal waters and resources. In response, Fisheries and Oceans Canada (DFO) established a program to detect and track the spread of aquatic invasive species in Canadian waters (2006). In the Newfoundland and Labrador (NL) Region, these species include biofouling organisms (tunicates, bryozoans, crustaceans, seaweeds), European Green Crab, and recently, several freshwater species (data not available at this time). DFO NL Science monitors for AIS in partnership with other DFO branches, the provincial government, Memorial University, including the Marine Institute, industry, first nations, and NGOs. Methods for detecting AIS used by DFO and their partners, include settlement plates, trapping, seining, eDNA (water samples), qPCR (species confirmation), SCUBA surveys along wharves, floating docks and vessel hulls, and video surveys at high-risk harbours. The data collected from DFO's monitoring program and their partners provides an overview of the distribution of AIS in the NL Region. This information can be used by the general public, scientists, and DFO managers.

Reference: Tunicates Golden star tunicate (Botryllus schlosseri) 2006 The Golden star tunicate was the first invasive tunicate detected in NL waters. It was reported in Argentia by the US Navy around 1945. It was found in 2006 on wharf structures in Argentia, Placentia Bay during the first AIS survey (Callahan et al 2010). This colonial tunicate is recognized by it star shaped grouping of individuals within the colony. It is currently found in Placentia Bay, Fortune Bay, St. Mary’s Bay, Conception Bay and the west coast of NL. The data provided here indicates the detections of this AIS in coastal NL. Violet tunicate (Botrylloides violaceus) 2007 The violet tunicate was first detected in NL waters in 2007 in Belleoram, Fortune Bay on wharf structures and vessels (McKenzie et al. 2016b). This colonial tunicate forms irregular shaped colonies usually of a solid color (orange, purple, yellow or cream). It is currently found in relatively small colonies in four harbours in NL; Placentia Bay (1), Fortune Bay (1), Conception Bay (1) and the west coast of NL (2). The data provided here indicates the detections of this AIS in coastal NL. Vase tunicate (Ciona intestinalis) 2012 The Vase tunicate, is a high impact solitary invader and was first detected by DFO in 2012 on the Burin Peninsula at Ship Cove and Little Bay, Placentia Bay. Various mitigation measures (McKenzie et al. 2016b) contained this invasive tunicate to a small area for six years within Placentia Bay. First detected in Fortune Bay as an established population in 2019, increasing reports of the Vase tunicate have been made along the south coast of Newfoundland. The data provided here indicates the detections of this AIS in coastal NL. Bryozoans Coffin box bryozoan (Membranipora membranacea) 2002 The Coffin box is a bryozoan (filter feeding animal) that forms white colored encrusting colonies, particularly on seaweed, but also on vessels and other surfaces. The cells are rectangular or “coffin box” shaped. It was first detected on the west coast of NL in 2002 and has since spread throughout the island, including southern Labrador. The data provided here indicates the detections of this AIS in coastal NL. Orange ripple bryozoan (Schizoporella japonica Ortmann) 2022 The Orange ripple bryozoan is an orange heavily calcified encrusting species found mainly on man made structures, rocks, shellfish, and vessels. It was first identified in NL in 2022 in Arnold’s Cove, Placentia Bay, but has likely been in NL for at least two years and is now suspected in several locations in Placentia Bay and Fortune Bay. A 2023 survey of the south coast of NL found several harbours invaded by this species. The data provided here indicates the detections of this AIS in coastal NL. Crustaceans (Biofouling) Japanese skeleton shrimp (Caprella mutica) 2006 The Japanese skeleton shrimp is tiny (1.5 -3.5 cm) and was first found on settlement plates in Placentia Bay during the first AIS biofouling survey in 2006. This species is currently found in many places in Placentia Bay, Conception Bay, Trinity Bay, and on the south coast of NL. This species inhabits, sometimes in large numbers (100,000s) ropes, moorings, and docks. The data provided here indicates the detections of this AIS in coastal NL. Seaweed Oyster thief (Codium fragile) 2012 Oyster thief is a green seaweed with thick spongy Y-shaped branches that resemble fingers (another common name is dead man’s fingers). This invasive species was first found in Placentia Bay in 2012. It is now found in several locations in Placentia Bay and Fortune Bay. It has also been found in one location in Notre Dame Bay. The data provided here indicates the detections of this AIS in coastal NL. AIS NL European green crab Fisheries and Oceans Canada's (DFO) AIS Science Program conducts annual field surveys to monitor the introduction, establishment, spread, and relative abundance of the European green crab in the NL region since 2006. Standardized monitoring and trapping protocols (McKenzie et al. 2022) are used by DFO's NL, Maritimes, Gulf, Quebec, and Pacific regions. The Fukui trap is the most commonly used trap but other methods are also used including shoreline collection, seining, and SCUBA dive surveys. Fukui traps have been deployed annually at both new and long-term monitoring locations throughout coastal Newfoundland and Labrador, particularly within Placentia Bay where they were first detected in North Harbour in 2007 (Blakeslee et al. 2010). It should be noted that there are two different populations of European Green Crab, a hybridized population in Placentia, St. Mary’s, and Fortune Bays and a cold tolerant population on the west and southwestern coast of NL (Lehnert et al. 2018). After initial detection in 2007, a separate invasion occurred in 2009 on the west coast of NL, and this cold-tolerant population is spreading eastward along the south coast toward areas inhabited by the original hybrid strain. The data provided here indicates the detections of this AIS in coastal NL. Should be cited as follows: DFO Newfoundland and Labrador Region Aquatic Invasive Species Green Crab Monitoring Program.

The Urban Atlas provides pan-European comparable land use and land cover data for Functional Urban Areas (FUA). The Street Tree Layer (STL) is a separate layer from the Urban Atlas 2012 LU/LC layer produced within the level 1 urban mask for each FUA. It includes contiguous rows or a patches of trees covering 500 m² or more and with a minimum width of 10 meter over "Artificial surfaces" (nomenclature class 1) inside FUA (i.e. rows of trees along the road network outside urban areas or forest adjacent to urban areas should not be included).
