Wild Parsnip, Poison Ivy, and Giant Hogweed are commonly found in areas of uncultivated land, roadside ditches, nature trails, woodlots, and in some cases, on rural and residential property. Under the Ontario Weed Control Act, the City is responsible to take some action regarding the control of Wild Parsnip, Poison Ivy and Giant Hogweed on city property. Private property owners are responsible for removing these plants from their own property. These plants are of public health concern because touching them or their sap can result in painful skin rashes and burns. If you decide to take measures to control these plants, regardless of the method used, wear protective clothing and goggles to cover exposed skin and protect your eyes.
Species which are quick to reproduce and spread, and which thrive in a broad range of habitat conditions, can often out-compete other species. These species are called “invasive” due to their aggressive colonisation of new spaces. Although some native species could be considered invasive, they are usually kept in check by the natural balance of their local ecosystem, and are not of great concern compared to non-native invasive species. Humans have transported many species to new lands, whether deliberately in the case of livestock, pets, crops and garden plants, or inadvertently in the case of many species commonly regarded as pests. These non-native species may have no local predators to control their spread, or may have devastating effects on local species which have not adapted to resist them. They can have serious impacts on the ecological balance of their new home.
Residents can help control invasive non-native species by becoming aware of them and acting to prevent or limit their spread. When camping, boating or cottaging, avoid transporting firewood or live bait into or out of the area, and clean all equipment thoroughly to remove seeds and other hitch-hikers. Never release unwanted pets into the wild. Choose native plants for landscaping where possible, and never plant non-native invasives (see some examples listed below) near natural areas. Ask your local nurseries and plant suppliers about which native species are best for landscaping, or use this handy ‘grow me instead’ guide.
Garden plants to avoid
Many non-native invasive species have already reached Ottawa. Garlic mustard, swallow-wort (also known as dog-strangling vine), common buckthorn and glossy buckthorn are common in many of our natural areas, crowding out the native species that should be there. Zebra mussels, Eurasian water-milfoil and flowering rush are thriving in our rivers. Other threats, such as the Asian long-horned beetle, are moving this way. Some species are still actively introduced, such as Norway maple and Amur maple, which are both popular landscape trees due to their attractive foliage and their ability to survive in highly urbanised environments. Others, such as the emerald ash borer that is decimating our city’s forests, are the subject of intensive research to find ways to control or eliminate them.
The following popular garden plants are non-native invasives that should not be planted near natural areas:
Pretty sure it does, something, something, protein, something, I forget, but somebody told me once that it makes hair grow faster.
I know weed increases you matabalism but does that mean your hair would grow quicker?
Only if vaporized
Wouldn't suprise me if it does
I don't know if there's some magic correlation between metabolic rates and hair growth but I smoke and I still can't grow a beard so I would have to say no.
I feel (my wife has said this multiple times also) that since I started smoking regularly I'm getting haircuts and shaving more often. so part of me thinks it's possible, or I just love believing stoner myths.
