We would suggest that there may be another underlying cause. However, having said this, governmental wildlife officials have for years misrepresented Mute Swans as being non-native, invasive and that they eat too much vegetation.

However, these are all blatant misrepresentations to have the public buy into killing the Mute Swans so the larger Trumpeter Swans can be introduced for Trophy Waterfowl hunting purposes. In fact, the Trumpeters are much larger, eat twice as much sub aquatic vegetation where fish and other plankton live and defecate twice as much into the pond as Mute Swans.

These officials have known these facts for years, but continue forbidding the introduction of Mute Swans while introducing as many captive and wild Trumpeters as possible. Eventually, if you have a permit for the Trumpeters, wildlife officials will begin taking juvenile cygnets and introduce them into other areas to increase population numbers for hunting. This is already occurring in other states.

We certainly do not want to soley blame your swans for the condition of the lake. There could be other factors such as run-off from area farms, roads, leaking septic tanks, drought, flooding, bad winter weather, etc.

You might want the water quality tested to see if there are fertilizers, pesticides, etc., that might be affecting your water and waterlife. The Regal Swan
