neighboring Stanhope Borough to tackle the<br />

goose issue on the lake, said Administrator<br />

Ralph Blakeslee.<br />

“It’s a health issue,” he said.<br />

Off-lake efforts include dog cut-outs, taller<br />

grass and other efforts to discourage the geese<br />

from landing on the grass lakeside and in parks<br />

where the waste can be washed into the lake<br />

and the Musconetcong River.<br />

“It makes a difference,” he said. “It’s a public<br />

service to keep the parks and lake cleaner.”<br />

Meanwhile, the Longwood Lake Cabin<br />

Owners Association in Jefferson makes “no<br />

community-wide interventions” to address<br />

geese, said Eva-Lee Baird, the group’s secretary.<br />

“Longwood Lake, formed by a dam on a<br />

small river, has a fairly high flow rate, [which]<br />

keeps a number of potential problems from<br />

becoming serious and avoids the need for<br />

community-wide interventions,” she said.<br />

Grace Rhinesmith, Jefferson Township’s<br />

director of parks and recreation, has been<br />

scheming against Canada geese for 20 years<br />

when the birds invaded the Lakeside Recreation<br />

Complex, which borders Route 15 South and<br />

is surrounded by a section of Lake Hopatcong<br />

known locally as the canals.<br />

The fields were covered with geese feces, she<br />

said. “It was a health issue for the players and<br />

was washing into the lake.”<br />

The township tried all the recommended<br />

mitigation efforts: Habitat disturbance,<br />

fencing, tall grass and egg addling.<br />

Early on, Rhinesmith, along with her then<br />

boss, Roland Sparling, supervisor of parks,<br />

would search for nests along the shoreline<br />

surrounding the park, addling as many eggs<br />

as they could find. It was a daunting task, she<br />

said.<br />

Soon after, the township enlisted the help of<br />

the U.S. Department of Agriculture, settling<br />

on a course of action that has shown significant<br />

improvement, said Rhinesmith.<br />

“There is a huge difference. We used to see<br />

20, 30, 40 geese a day [on the fields]. It’s gotten<br />

a lot better over the past decade.”<br />

The number of nests and eggs addled varied<br />

over the years, said Rhinesmith.<br />

In 2003, the first year, 101 eggs were addled.<br />

In 2005, 30 nests were found and 151 eggs<br />

were addled.<br />

In 2011, there were 11 nests and 30 eggs<br />

addled.<br />

In 2021, there were 18 nests and 87 eggs<br />

addled.<br />

April Simnor, a USDA wildlife biologist, has<br />

been tasked with addling in Jefferson for the<br />

last 16 years, spending countless hours in her<br />

kayak searching for nests hidden among the<br />

vegetation along the shorelines in the canals<br />

and around Liffy Island and other lakeside<br />

township-owned property.<br />

On a recent April morning, Simnor paddled<br />

her way a short distance in the canals, checking<br />

the first half dozen known nests along the route<br />

and encountering three pairs of protective<br />

parents along the way.<br />

The success of addling, in which Simnor<br />

terminates the growth of the embryo by oiling<br />

the egg and returning it to the nest, is to trick<br />

sitting adults into believing the egg is still<br />

developing.<br />

On this day, three nests were “active” with<br />

sitters while three others were abandoned,<br />

flooded out due mostly to the high-water level<br />

in the lake at the time.<br />

At its April meeting, Simnor, who comes<br />

with an impressive resume, advised the lake<br />

commission on its goose mitigation program.<br />

(In 2019, she was the lead biologist on a<br />

program to disperse tens of thousands of crows<br />

from the state government complex. That same<br />

year she led an effort to reduce the impact of<br />

Canada geese on the properties operated by the<br />

Passaic Valley Water Commission.)<br />

In her presentation, Simnor focused on<br />

employing many of the current techniques,<br />

advised the commission on current laws and<br />

highlighted the need to secure permission from<br />

property owners for access to their properties<br />

to seek nests.<br />

“Lake Hopatcong is a challenge because of<br />

its complex watershed and the size of the lake,”<br />

Simnor said.<br />

The effort to move geese is complicated, she<br />

said.<br />

Tall grasses along a lake can offer a hidden<br />

nesting area, for example, she said, but also<br />

raise concern among the geese because they<br />

might not be able to see a predator.<br />

That might make the geese seek another<br />

nesting area, she said.<br />

Yet that is also tricky, Simnor said.<br />

Geese might respond to persistent efforts<br />

to disrupt their habitat, she said, but they are<br />

genetically attached to their birthplace, like<br />

many animals.<br />

So, while humans want the geese to find<br />

another home, if they were born there, Lake<br />

Hopatcong is their home.<br />

Simnor said the last data from USDA showed<br />

there are 68,215 Canada geese in New Jersey.<br />

That would be a drop of about 12,000 from<br />

2008, as measured by Rutgers.<br />

“Making a consistent effort is the key” to<br />

reducing the goose population, said Jefferson’s<br />

Rhinesmith. “These birds are harmless in one<br />

sense—they are not predators, but at the same<br />

time they are dangerous because of what they<br />

leave behind.”<br />

For Karen Porfido, the effort is about looking<br />

ahead.<br />

“I want the lake to be clean for my children<br />

and grandchildren,” she said.<br />
