write a report on ravines
Answers
Explanation:
Toronto’s ravines, which cover 17,000 acres, are valuable in so many ways. They provide essential ecological services, including flood protection and cleaning the air; they make our properties more valuable and provide abundant mental health benefits. And for a few kids that can peel their eyeballs from Instagram for an afternoon, they are an unparalleled place of recreation and imagination.
Yet if you head into any ravine in the Don Valley today, alongside a myriad of native species from towering oak to brightly coloured sumac there are invaders storming the flora gates. According to a new ravine study, the growth of invasive species is one of the main culprits pushing the ravines to the verge of collapse and putting at risk one of the city’s defining and most beloved features.
A few years back, TD Canada Trust valued the city’s urban forest at a whopping $7 billion. So why is the city letting it all happen?
Sure, Toronto has produced a ravine strategy, but it is, according to some critics, more focused on human connection to the ravine and less on the science that would preserve the ecosystems for future generations.
Report on ravines:
- Ravines are landforms of narrowing deep valley with steep sides but it's different from the canyon. It can be described as a smaller landform with narrow deep valleys having steep sides, comparatively small than canton but larger than a gully.
- Formation of these takes place by the action of the stream that generally erodes the land thus having an active stream around the year. They are smaller but long and several hundred feet wide, found in lower mountain or hills regions that have changing land features.
- There are many examples of the same as Sage USA, Rosedale Canada; the former is also a popular scenic hiking site.
