Aquatic invasive species present in Otsego County, NY water bodies

Annie Yoo1, Kaylee Herzog2, and Holly Waterfield CLM3

INTRODUCTION

Otsego County, located in central New York, experiences increased populations in the summer months largely related to tourism and outdoor recreation. Abundant water resources in the county, combined with this increase in summer traffic contribute to the risk of invasive species transport between water bodies and major watersheds. Knowledge of the current distribution of invasive species will allow natural resource managers to prioritize transport prevention and population control measures.

Exotic invasive species are those not native to an area that outcompete native species. Such exotic, non-native species typically possess traits which, in combination with lack of natural disease and/or predators, allow them to out-compete native species (Santos et al. 2011) and in-so-doing have negative ecological and economic impacts. Some of these impacts include productivity losses in agriculture, forestry, and other segments of the U.S. economy (Pimentel 2005). Aquatic invasive species (AIS) pose major threats to biodiversity in ecosystems. They often overtake important native aquatic plants and animals, cause habitat degradation and loss, and interfere with water-based recreational activities (Zhang and Boyle 2010). Pimentel (2005) suggests it is difficult to estimate the full extent of the environmental damages caused by invasive species and the number of species extinctions they have caused because little is known about each of the ~750,000 species present in the United States. In most cases AIS are initially introduced to watersheds through recreational boating activities or unintentional “hitchhiking ” (Horvath 2008), which can occur through international trade, with invaders stowed in ships, planes, trucks, or packing materials (McNeely 2001).

Aquatic invasive species and their impacts have been the subject of BFS research since its inception in 1968. In terms of surveys to document AIS distribution, surveys were conducted in 2011 to assess AIS in the Catskills region (Harman 2012), but no studies have involved a county-wide assessment in Otsego County. This study was conducted to evaluate the presence/absence of aquatic invasive algae, vascular plants, zooplankton, and invertebrate benthos present in the water bodies of Otsego County, New York.

MATERIALS AND METHODS

Eighteen lentic systems and 9 lotic systems (Table 1, Figure 1) were assessed for the presence of 24 exotic species (Table 2). Survey sites were chosen based on accessibility and also to achieve relatively even coverage of water bodies across the county, ensuring that the major water ways and water bodies were assessed. Sites chosen for the survey included NYS DEC Boat Launches and Public Fishing Access Points, as human traffic (and associated activities and

equipment) is the main vector for transport of invasive species from one locale to another. Additional survey sites for lotic systems were included at all accessible road-crossings. A complete listing of all site locations is provided in Appendix 1. Species not listed in Table 2 were not specifically searched for, though would have been noted if found.

Bottom composition and substrate conditions were characterized for each site, and the presence of a Department of Environmental Conservation angling access or boat launch site was noted. GPS coordinates (datum: NAD 1987) for each survey site were recorded using a Garmin GPSmap 76CSx.

Lentic Systems

Sixteen of the 18 lentic systems in this survey were examined via canoe. Permission was sought for access from private sites or onto water bodies with restricted public access (i.e., reservoirs, private residential communities). Observations were also made on shore. Presence of invasive emergent plants was assessed along shorelines, and benthic species were assessed by scanning the available hard substrates. Submerged vegetation was collected by hand-picking shallow rake tosses (two to four sites per system, dependent upon water body size and variability of substrate). Plankton samples were gathered using tow nets (80µm mesh). Otsego and Canadarago Lakes were not directly sampled during this survey due to the size and complexity

of the systems; presence of invasive species was determined based on recent surveys by BFS personnel (i.e., Canadarago: Albright and Waterfield 2012; Otsego: McShane and Mehigan 2013, Tanner and Albright 2014, Vanassche and Wong in prep).

Lotic Systems

Several locations were sampled along each of the nine lotic systems in this survey, resulting in a total of 76 sampling sites. Riparian areas were assessed at each site for the presence of invasive emergent plants. Seining, dip-netting, hand-sieving and hand-picking were also employed at each site to assess the presence of invasive invertebrates.

Equipment Sterilization and Sample Preservation

At the conclusion of sampling in each location, all equipment was removed from the water and rinsed on-shore with a diluted bleach or rock salt solution. Any organisms which were inconclusively identified on site were saved, marked with collection data, and transported on ice to the laboratory for definitive identification. Plankton samples were transported on ice to the laboratory, preserved with 70% ethanol, and analyzed under a dissecting microscope.

Mapping and Data Portrayal

Waypoints stored at each site were uploaded electronically using Global Mapper™ software. Information regarding the presence or absence of invasive species at each site was attached to each waypoint and graphically represented using ESRI ArcMap software. Data will also be uploaded to iMapInvasives, an online, GIS-based data management system used by citizen scientists, researchers, and natural resource managers to document, assess, and coordinate the management of invasive species.

RESULTS AND DISCUSSION

Observations are summarized graphically in Figures 3-7 and in tabular form in Tables 3 and 4. Eight of the 24 surveyed species were observed in at least one location; this survey did not document the presence of any species previously undocumented in the county, though water chestnut, a high-priority species, was found in a new location. The species found were Orconectes rusticus, Trapa natans, Fallopia japonica, Myriophyllum spicatum, Lythrum salicaria, Potamogeton crispus, Nitellopsis obtusa, and Dreissena polymorpha.

Of the sites surveyed, invasive species were found at 48 stream sites, representing 8 of

the 9 lotic systems, and in nine of the 18 surveyed lentic waterbodies (Figure 3, Tables 3 and 4). Sites containing the greatest number of AIS were lentic systems, the top three of which were the three largest lakes included in the survey, Canadarago Lake (7 spp.), Goodyear Lake (5 spp.), and Otsego Lake (7 spp.). A brief overview of each species observed is provided in the following paragraphs.

Orconectes rusticus (rusty crayfish) is the most prolific invasive crayfish in the US.

Native to the Ohio River drainage, rusty crayfish have been spread to 15 states outside of their native range, primarily though bait-bucket introductions and also by releases from science classrooms (Olden et al. 2006). It inhabits lakes, streams, and rivers, preferring habitats where debris for cover is present (Gunderson 2008). Once introduced to a water body, rusty crayfish quickly displace native species of crayfish and result in cascading trophic impacts due in large part to their aggressive behavior and higher metabolism and food consumption (Gunderson 2008). Rusty crayfish were first documented in the upper Susquehanna River drainage in 1991 (Kuhlmann and Hazelton 2007).

Trapa natans (water chestnut) is a Eurasian macrophytic plant that occurs in dense beds

of floating rosettes. It was originally introduced into North America as an ornamental plant, but is now present in lentic water bodies from Virginia north to Vermont in the US and in the province of Quebec in Canada (U.S. Dept. of Agriculture 2013). The dense beds impede recreational activities, displace submerged native plant species, alter littoral bentic inverteberate and epiphytic community composition, and greatly alter the environmental conditions the waters underneath, including increasing summer temperature, creation of anoxic conditions, and decreased light availability (Hummel and Kiviat 2004, Kornijow et al. 2010).

Native to Asia, Fallopia japonica (Japanese knowtweed) was first introduced into Europe

in the mid-19th century and had rapidly invaded areas in the USA by 1877. It is easily identifiable by its hollow, bamboo-like stems that grow in excess of 3 m high. It is most commonly found in riparian zones where water is readily available, but is also common along upland roadsides. Its invasion occurs through the process of colonizing rhizomes, allowing the plant to quickly displace native plant species and reduce area for other animals to survive (Forman and Kesseli 2003).

No AIS found: Wharton Creek 2-6 Myriophyllum spicatum (Eurasian watermifoil) and Potamogeton crispus (crispy

pondweed) were introduced to North America from Europe (Santos et al. 2011). These are submerged plant species that have the ability to rapidly dominate aquatic systems through the formation of dense beds that displace native vegetation, reduce phytoplankton densities and open water nutrient concentrations, and impede recreational activities. Past studies have proposed that their competitive advantage and ability to rapidly colonize an area lies in their use of auto fragmentation and lower light and CO2 requirements (Gross et al. 1996).

Lythrum salicaria (purple loosestrife) was initially introduced to North America in the

early 1800s and has since spread throughout the continent. It is now present in all lower 48 states with the exception of Florida. It has been declared as a noxious weed because of its negative impacts to wetlands, bog turtles, and mammals (Blossey et al. 2001). Many actions have been taken to stop spread of this plant or control established populations, though physical controls such as flooding, burning, and mowing are expensive and have had little or no long term

effect. Biological control has been successful in reducing the density of L. salicaria and controlling populations over decades of monitoring (Albright et al. 2004). Populations documented in this survey may be targeted for establishment of Galerucella beetles in order to combat spread and recover native wetland plant communities.

Nitellopsis obtusa (starry stonewort) is an exotic charoid macroalga that has been present

in Lake St. Clair since 1986. It can be identified by its starry rhizoids that are present in all parts of the plant at all times of the year in Michigan Lakes. It is light green colored when actively growing and its stem-like thallus is comprised of a single cell. Like previously described invasive submerged plants, it forms dense beds up to 2 m in thickness, out-competing native plants and drastically altering the littoral zone habitat (Pullman and Crawford 2010).

Dreissena polymorpha (zebra mussel) was observed in a number of locations throughout

the county and is widespread across the continental US. It is one of the more dramatic invasive species due to its rapid range expansion and immediate economic impacts. Zebra mussels have directly affected native unionid clams; the species displaces native clams by attaching to their hard outer shell, essentially causing them to suffocate and/or starve. Unfortunately, it is easily transported to new water bodies as a free-floating larva or in the adult form attached to equipment, plants, etc. For example, any activity that can move water within or between water bodies can greatly accelerate the spread of D. polymorpha (Johnson and Carlton 1996).

This study along with other research on the transport, establishment, and growth of AIS

may help natural resource, specifically lake, managers understand the biology of invasive species and prioritize prevention and control measures within Otsego County. Furthermore, it may help raise public awareness of impacts on biotic resources, water quality, cultural and recreational activities.
