The Adirondack Park Invasive Plant Program (APIPP) is one of eight Partnerships for Regional Invasive Species Management (PRISM) in New York State whose mission is to protect the Adirondack region from the negative impacts of invasive species. The Adirondack Watershed Institute (AWI) is a program of Paul Smith’s College that conducts work to protect and conserve water resources of the Adirondack Park. The narrative, data, and results presented in this report were synthesized by Sean Regalado, Lindsey Pett, Peter Murphy, and Nathaniel Wells who constituted APIPP’s Aquatic Invasive Species (AIS) Regional Response Team in 2017. These individuals also conducted the aquatic plant surveys and performed the spatial analysis needed to develop the lake maps featured in this report. Project planning and lake prioritization was conducted by Erin Vennie-Vollrath, APIPP’s AIS Project Coordinator, Dr. Daniel L. Kelting, AWI Executive Director, and Sean Regalado, Response Team Lead. Field work and reporting was conducted with the assitance of Dr. Kelting and under the additional supervision of Dr. Corey Laxson, AWI Research Associate. This project was advanced by APIPP, under contract with AWI, with funding provided by New York State’s Environmental Protection Fund.

Aquatic invasive species (AIS) induce negative ecological impacts on aquatic ecosystems and local economies (Gallardo et al. 2016; Walsh et al. 2016). In attempts to reduce these impacts, government and private entities at multiple scales have implemented AIS spread prevention and early detection efforts (Vander Zanden et al. 2010). APIPP and AWI, in collaboration with multiple partner organizations, utilize state, federal, and private funds to implement AIS prevention, early detection and rapid response strategies across the entire Adirondack PRISM.

Since 2015, APIPP has contracted with AWI to deploy AIS response teams in the PRISM. In order to balance resources and increase efficiency, the PRISM was broken into three regions based on watershed boundaries (Fig. 1). One region received survey focus each year to facilitate survey of the entire PRISM on a three-year rotation. Region 1 (Upper Hudson, Sacandaga, Mohawk, and Southern Champlain watersheds) was surveyed in 2015, Region 2 (Black, Oswegatchie, Grass and Raquette watersheds) was surveyed in 2016, and Region 3 (St. Regis, Salmon, Chateaugay, Great Chazy, Saranac, Ausable and Northern Champlain watersheds) was surveyed in 2017. This report details the work undertaken by APIPP’s AIS early Figure 1. Map of Adirondack PRISM AIS detection/rapid response team in Response regions. Region 3 over the course of the 2017 summer field season.

Page 2 Objective

The 2017 response team’s primary objective was to detect and document the distribution of aquatic invasive plant infestations through systematic vegetative surveys in prioritized lakes. The team also monitored each lake for invasive animals such as spiny waterflea (Bythotrephes longimanus), using plankton tows, and Asian clams (Corbicula fluminea), using sediment sieves. A secondary objective of the team was to perform rapid response management on any new, small, isolated aquatic invasive plant infestations discovered. APIPP’s AIS Project Coordinator, Erin Vennie- Vollrath, used GIS and land use characteristics data for the region as well as local knowledge and expertise from AWI and partners to prioritize region 3 lakes to be surveyed by the response team in 2017 (Table 1). Lakes over 4,500 acres in size were excluded from the selection process due to time and resource constraints; one exception being Cranberry Lake. APIPP hopes to balance resources by utilizing response teams to survey one large Adirondack lake (>4,500 ac.) each summer. Additionally, lakes under 5 acres and lacking a public launch were excluded given the absence of anthropogenic AIS invasion pathways. The remaining lakes were prioritized in GIS using the following criteria:

Priority 1

- Lakes having a public boat launch that have never been monitored. - Lakes having a public boat launch that have only been partially monitored for AIS in the past three years. Priority 2

- Lakes having a public boat launch that have not been professionally monitored for AIS in the past three years. Priority 3

- Lakes having a public boat launch that were last professionally monitored for AIS in 2015. Priority 4

- Lakes having a private boat launch that are monitored annually for AIS by volunteers. - Lakes having a public boat launch that were last professionally monitored for Page 3 AIS in 2016. Table 1. List of Priority Lakes for 2017 Objective

Aquatic plant surveys

The response team conducted comprehensive aquatic plant surveys of each lake’s littoral zone using a combination of visual surveys, rake tosses, and snorkeling. Each crew was equipped with a bathymetric map of the lake, portable depth sounder, handheld GPS unit, two-sided rake toss, snorkel and fins, and a 4 digital camera.

Aquatic plant beds were found by paddling in a serpentine pattern from the shore to the edge of the littoral zone. The boundaries of aquatic plant beds were estimated using rake tosses and a handheld depth sounder, and then marked by taking GPS points. Percent cover estimates were taken for each plant species with an abundance score of 1 (rare, <5% coverage), 2 (occasional, 5 to 15% coverage), 3 (present, 16 to 25%), 4 (common, 26 to 50%), or 5 (abundant, >50%). Taxonomic ID of aquatic plants followed the dichotomous keys of Crow & Hellquist (2000). 3 Visual surveys were supplemented by periodic (and equidistant) rake tosses. For each rake toss the GPS location was taken and depth recorded. A species list and abundance estimate (1-4) was made for each species (Fig. 2). Often the water clarity hindered the surveyor’s ability to see the lake bottom where basal aquatic plants could be growing. Supplemental rake tosses allowed the surveyor to estimate the true spatial extent of plant beds as well as increase the probability of discovering AIS infestations.

At least four snorkel sites per lake were also selected to further verify species composition and abundances. These sites included 2 the area surrounding each boat launch as well as three of the most species rich plant beds according to visual survey and rake tosses.

Once the full species composition of the snorkeled bed was ascertained, newly found species were appended to the visual survey findings. All field data was collected via paper data forms and entered into GIS to create lake specific aquatic plant maps. The National Hydrography Dataset waterbody shapefile was used to create these maps. Figure 2 1 Page 5 Methods

Point Intercept Plant Survey Method

In 2017, the AIS response team introduced the point intercept method to survey lakes that had littoral zones that were too expansive to be surveyed efficiently using the serpentine pattern method (Fig. 3). The point intercept method deploys rake tosses and depth sounds along transects throughout the entire lake (see Oseetah Lake pg. 57). Data from this method can be used to produce bathymetric maps and quantitative estimates of aquatic plant densities. This methodology was utilized on Oseetah Lake, Chazy Lake, and in select bays of Cranberry Lake.

Aquatic animal surveys

For each lake, a 500 micron plankton net was used to sample the lake’s plankton community for the presence of invasive waterfleas. The team utilized two plankton tow methods: 1) a vertical tow (bottom to top) retrieved as fast as possible and 2) a horizontal tow initially dropped to the estimated thermocline and then towed by canoe as fast as possible for one minute. The plankton samples were preserved with formalin or alcohol and examined in the field and in the lab with a dissecting microscope. At boat launches and access points with coarse, sandy substrates, a 2mm test sieve was used to monitor for invasive molluscs. At each location seven sediment samples were collected in a ray pattern (Fig. 4). All organisms retrieved from the sieve were added to a Figure 4.

Between June 5 and August 30, 46 lakes and ponds were surveyed by the response team (Table 2, Map 1). Of these lakes and ponds, 18 contained at least one AIS. All invaded lakes contained previously documented AIS infestation(s). No newly invaded lakes were discovered. Eurasian watermilfoil (Myriophyllum spicatum) was the most common AIS found (16 lakes), followed by variable leaf milfoil (M. spicatum) (eight lakes), and curly leaf pondweed (Potamogeton crispus) (three lakes). No infestations of invasive animals were found.

A total of 431 miles of shoreline was surveyed by the response team in 2017. On average each lake took approximately 6.7 hours to survey, ranging from 30 minutes for the 14 acre Pink Pond to 50 hours for the 6903 acre Raquette Lake. On average, the four person team surveyed each lake’s shoreline at a pace of 1.4 hours per mile and each lake’s littoral area at a pace of 15 hours per acre.

Approximately 4655 acres of plant beds were surveyed and mapped. Plant beds ranged in size from 43 square feet to 576 acres, averaging approximately 7 acres. 2857 rake toss samples were retrieved, of which 1270 returned plant samples.

Aquatic Plant Diversity

In 2017, 56 aquatic plant species were identitifed. The three most abundant plant taxa found were spadderdock (Nuphar variegata) in 45 lakes, bur-reed (Sparganium sp.) in 42 Lakes, and ribbonleaf pondweed (Potamogeton epihydrus) in 40 lakes. The five least abundant plant taxa found were duckweed (Lemna minor) in one lake, low milfoil (Myriophyllum humile) in one lake, longbeak buttercup (Ranunculus longirostris) in one lake, snail-seed pondweed (Potamogeton bicupulatus) in one lake, and water chestnut (Trapa natans) in one lake. See community matrix on page nine.

On 6/15/2017 the team returned to Lake Alice (Clinton County) to manage a water chestnut infestation that was discovered in 2016. The team removed 30 water chestnut plants (Trapa natans) from a 4’x5’ area (44.86585, -73.48611). The team returned on 8/4/2017 but did not find anyadditional water chestnut plants.

On On 6/20/17 the team returned to Loon Lake (Warren County) to manage a historic water chestnut infestation discovered in 2015. Twelve water chestnut plants were removed from two locations (43.69248, -73.85143 eleven plants; 43.69253, -73.85075 one plant).

Eurasian watermilfoil (Myriophyllum spicatum) has been documented in Meacham Lake (Franklin County) since 2002. The historic distribution within the lake has been limited; in 2010 eight sites were identified. On 7/3/2017 the team removed ~20 plants from seven of the historic locations. The final site, a 3-acre area east of the south inlet which had 20+ plants, was not managed because it was densely populated by native species relative to the other sites. This site would have required a full day of work with a diver assisted hookah to remove the invasives while not disturbing native plant species.

On 7/27/2017 the team hand harvested variable leaf milfoil (M. heterophyllum) and Eurasian watermilfoil from an area adjacent to the boat launch on Fish Creek Pond (Franklin County). Twenty bags of invasive milfoil were removed. This location was prioritized for management in order to reduce the likelihood that boaters accessing or exiting this popular lake would transport invasive material to uninvaded lakes in the region.

Curly leaf pondweed (Potamogeton crispus) was found in three plant beds in Lower Saranac Lake (~12 plants), one plant bed in Lake Flower (two plants), and one plant bed in Kiwassa Lake (one plant). These plants were removed. The distribution of these invasive plants was limited, and therefore, management was deemed appropriate.

On 8/23/2017 the team hand harvested one bag of variable leaf milfoil from Paradox Bay in Lake Placid (Essex County). Variable leaf milfoil was first reported in Lake Placid in 2009. Since then, annual management has been coordinated by the Lake Placid Shore Owners' Association. This annual management effort has kept the infestation very small. Due to a scheduling conflict, there was concern that management would not be completed in the summer of 2017. To ensure that there would not be a lapse in management, the team was deployed.

In the future, APIPP intends to deploy response teams at all of these historically managed infestations to evaluate progress and determine if additional or expanded management is warranted. Page 10 Data Limitations

The methodologies utilized to inventory the aquatic plant communities of prioritized lakes have shortfalls relating to species abundance estimates and GPS accuracy.

The serpentine search pattern utilized in our methodology maximizes the total area covered per time spent on each lake, but may suffer statistically by not stratifying species abundance estimates. Other methodologies used for aquatic plant surveys, such as transect and point intercept, conversely sacrifice area covered and efficiency for more statistically rigorous estimates of species abundance (Madsen 1999) (Fig. 6). Rigorous assessments of survey methods in other systems have found simple visual searches are the most cost effective when the goal is complete community inventory (Ellison et al. 2007). However, statistical analysis of visual searches relative to aquatic plant communities has yet to be done.

The Garmin® GPS receivers utilized during our surveys provided 10-foot accuracy. Due to their open nature, lakes offer a study system where interference from solid objects is minimal. Random accuracy checks throughout surveys often confirmed accuracy of 10 feet. However, this 10-foot variance likely affected the reported size of plant beds mapped.

Estimates of Survey Comprehensiveness

Ecologists often compare species richness across locations to determine how environmental and anthropogenic influences impact species diversity and distribution. However, sampling among sites is not often stratified, especially when the size and structure of the targeted areas differ significantly (Gotelli & Ellison 2013). With regards to the sampling methods described in this report, the number of plant beds found and rake tosses performed per lake varies and is usually tied directly to the size of each lake. For example, Lower Saranac Lake had 102 beds and 268 rake tosses performed while Hoel Pond had 12 beds and 79 rake tosses performed. These lake and survey specific differences make it difficult to determine which lake was surveyed more comprehensively.

Fortunately, numerical ecologists have developed a statistical method to estimate the true diversity of locations in a framework that allows for comparison of locations without bias. This method is called asymptotic estimation or colloquially, “candy-jar sampling” (Gotelli & Ellison 2013). This method was used to build a probability based coefficient for predicting richness.

Once richness for each lake was predicted it can be compared to the observed richness in order to determine how comprehensive the survey was. For example, if we observed 26 species and predicted 37 in Cranberry Lake while at the same time we observed 26 species and predicted 29 in Union Falls Pond, we can conclude that Cranberry Lake still requires more survey effort while Union Falls Pond was more comprehensively surveyed. Table 3 shows the observed and predicted species richness by lake surveyed in 2017, and is ranked by the difference between observed and predicted. Higher ranked lakes likely require more survey effort than was employed in 2017. For more information on the asymptotic estimator used see Chao and Jost (2012).
