Hi, I just attended some more grass training - and came up with some good suggestions - since the natural areas do not require water or fertilizer - then why not throw down some seed for natives?
>> I have attended a session on Grasses in Richmond Botanical gardens (2017) and also attended another class this year (2018) in Pennsylvania with Mike Berkely on Native Grasses to plant. The suggested grasses (when contained) were excellent choices. A few suggestions that were given and I would agree with were Purple Love grass - Eragrostis spectablis, Pink Muhly grass -Muhlenbergia capillaris (do not water or fertilize for control reasons), Northern Sea Oats - Chasmantium latifolium when not watered works well - (formerly Uniola) was considered a threatened species in PA and Michigan. I would suggest avoiding Mexican feather grass which when out of its native dry native S.W range becomes invasive, River Oats work well when not watered or fertilized, American beak grass - Diarrhea americana which should not be watered either and is a native bunch grass divided now into two different species - the other species is Obovate. Bushy bluestem, Elliots blue stem, Green Foxtail - Setaria viridis, is an annual and does not require watering and Poverty oats -Danthonia spicata. Some of these might not be a favorite of Virginia Tech - as they get in the way of agricultural crops but they are native and are preferable to Fescue or the worst invasive Johnson grass which produces the same type of growth habit when not mowed and does not have any native biological controls. This assists because the natives might replace some of the other invasive as they are very drought tolerant and hardy. Kathryn Peterson Lambert

A good proportion of the species in the herbaceous and shrub layers may be native but the vast bulk of the green biomass is non-native?the stu?ff we pick through, hoping to find a native plant somehow hanging on. Next time you?re in the ?eld with your camera, try for a photo showing three or more plant species, but not showing any non-natives. It isn?t easy. There?s bound to be a ground ivy or a multifora rose lurking in there somewhere. But you already know this.

But as long as the native plants continue to lose the competitive battle, it?s a hopeless cause. e non-natives have a major helper on their side, namely the white-tailed deer, an animal that, like many non-native invasive species, has no predators (other than humans) to curb its population. It is interesting to note that many of our non-native invasive plants, such as garlic mustard, have existed here for centuries, yet their numbers didn?t explode until the late 20th century ? along with the exploding deer population.

On behalf of MNPS, I recently attended a stakeholder meeting at which DNR solicited input from hunters, conservationists, state and federal government agencies and others. I was pleased to hear that reduction of Maryland?s deer herd remains a priority. DNR plans to hold public meetings during the summer. I hope our members and friends will participate to support eff?ective deer management in Maryland.

A team writing a bill for safe drinking water sat down with a team preparing a bill for fish and wildlife. Congress had to pass it. So we should work with our partners concerned about Lyme disease, deer car collisions, trees costing millions to remove when they fall on highways and power lines because of invasive vines such as English Ivy Oriental bittersweet and Japanese Honeysuckle.
