Management of Habitat Greenspace at the Valentine Mill Pond

July 22, 2019. These are notes used while speaking on KVSH radio in Valentine on their comment program. On the air for about 10 minutes.

There is a bit of land on the north side of Valentine which has value as greenspace and natural habitat. It is a place for wild birds. Flora thrives. This Mill Pond place is a unique setting and is an asset of Valentine.

In late summer of 2016 some pictures were taken of the triad of warm season grasses – big bluestem, Indian grass and switchgrass. They were growing so beautifully, and being so picturesque with a sky background. Water hemlock was a haven for a healthy caterpillar.

What does a grass space mean? To me it is a place to enjoy the natural setting and where to appreciate floral features vivid against a heart city sky of blue. It is worthy of special recognition. This is a place special to me as a very nice asset of the local landscape. I view this place nearly every day during my travels.

The space is however being treated wrong. Every year the vegetation is destroyed with intent at the Mill Pond. The current management is a policy of destruction of features so vibrant and significant. There has been grass growing upward to the sky. The setting is quite lovely.

Mowing is done without consideration of nesting birds. A territorial Common Yellowthroat has been present this season. Its voice has been prevalent. Did the destructors consider it presence? Nope, is what I was told by NRD staff. The Migratory Bird Treaty Act may have been violated since it states that is illegal to destroy bird nests and young. This action in simply wrong. There was no consideration taken to evaluate whether the setting has any value as pollinator habitat.

This property is owned by the City of Valentine and the Middle Niobrara NRD. The city defers management decisions to the NRD and is currently satisfied on how the site is managed, according to the city manager.

The primary purpose of the tract is to provide an emergency spillway for the pond. Therefore it is mowed annually to ensure there is no growth of woody vegetation and to have a surface conducive for a ready flow of water. This is a secondary overflow measure as the primary overflow feature is the drain pipe which empties into Minnechaduza Creek, below the dam. This was well used in March when water levels in the pond were excessive.

A mistake being made on this tract is the timing of the mowing, in my view. Mowing in July destroys the thriving warm-season grasses and turns a vibrant green space into barren bit of landscape. Windrows of cut grass are left behind and which stifle any potential regrowth.

A spring mowing would help inhibit the growth of cool-season grasses and increase the viability of the more preferential warm-season grasses.

I am hoping to meet with the city and NRD to determine if there could be any changes that might increase the value of this public space.

It should also be noted that there is no management plan for the tract, which could address the multiple use options for the grassy habitat and allow interested members of the public to provide input.

Potential recognition of multiple uses could include educational interpretation (variety of tall-grass prairie plants), pollinator habitat (develop and increase forb species; freely available seeds could be thrown out a few times and eventually they will grow) and management versatility (meet requirements of primary purpose while also developing additional values).

It is time to make this little habitat space the best it can be. This is not the case now in my opinion. I may be speaking alone but I can guarantee that others care.

Valentine has a lot of assets and I’d like to see them all appreciated and that includes a grassy bit of space at the mill pond?
