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 />
