Russian Olive - a very invastive plant has changed the landscape of NJ hunting

The thread related to "30 years ago" got me thinking about this very disturbing plant.

Invasion Biology Introduced Species Summary Project - Columbia University

http://www.invasivespeciesinfo.gov/plants/russolive.shtml

For those of you that remember what the State and federal lands looked like all around Sandyston and Wallpack, and even most of the Whittingham tracts many years ago, this plant did not exist. It completely took over much of the open ground that didn't keep up with field and brush mowing. I had heard that the state is who actually introduced this extremely invasive species, possibly to provide bird habitat. I believe it probably was introduced around 25 to 30 years ago.

This plant is difficult to cut, it dulls chainsaws, grows rapidly, has spikes, and spreads like wildfire and can completely take over a field or open lot in just a few years time. It's all over my neighborhood.

I often wonder if it has a direct correlation to the influx and population boom of the NJ black bear.
a) It provides terrific bear cover - so much of it grows next to houses and a lot of newer developments. The bears can lay in that all day long and nothing bothers them.
b) Major food source in the fall. When the "olives" ripen (big red berries) the bears load up on them. This is around the time I start seeing the most bears, and their feces becomes laden with it. My dearly departed Golden Retrieve used to roll in it, my how pleasant that was!

Bottom line - this invasive plant has also reshaped the landscape of NJ hunting - literally!

Do you know the plant I am talking of? What are your thoughts?
Would love for a real biologist to weigh on this.

I can tell you - it's never going away, it's impossible to eradicate....

I have often heard it referred to as "autumn olive" too. Actually I believe that is the plant I am talking about. There may be two species...
So I guess it really is "AUTUMN OLIVE" - the big problem we have here in NJ... (BEAR CANDY)

About the Invasive Autumn Olive | The Nature Conservancy

"According to The Nature Conservancy, autumn olive is quickly becoming one of the most troublesome shrubs in central and eastern United States".

This describes it pretty well - also called AUTUMNBERRY and is actually edible and full of lycopene..

I guess I will have to pick some next fall and try it!

We spend at least 4 days every year with the nature conservancy removing Russian olive. Lots if hard work. But the woods look a lot nicer when it's gone

State did initially plant it as "wildlife habitat" and now they are trying to eradicate it. It is just one in a multitude of invasive species of which the list grows longer, seemingly every year. It's actually quite alarming if you start looking around the outdoors and take the time to ID all of the invasives that are not only replacing native plant species but also ruining sensitive habitat for many wildlife species.

Little M got it right - we all moan about this and that, meanwhile something like this floats under the radar and we just accept it... I am telling you - as much as a loon probably half of you think I am by now, this single species (plant) has impacted hunting in NJ probably more than any other factor... It PHYSICALLY changed the landscape - and is growing about as fast as muslims!

Trees I hunted 15 years ago and shot the field edges I can't now due to the autumn Olive trees that border the fields the only shots I get are 30 yards out... Gotta prune them every year.

we also team up with Hunterdon land trust and cut them down for them on certain properties

my dad says he remembers a long time ago when you bought a hunting license they came with seeds to plant.. He said no one he knew planted them except him and his brother used to always plant them. He swears he thinks they were memes some type of olive seed...

Anyone renember? It was before my time.. Maybe 70s

wouldnt surprise me jerseyjay if they were russian olive seeds......over the years wildlife departments across the country have done things that later prove to be detrimental to wildlife as science and biological studies of wildlife and habitat continue to progress. i have a professor who was contracted in the 70"s to remove downed trees from the columbia river in the northwest because they thought that it would lessen the flooding and improve salmon populations.....now he is contact with former co workers who are currently working to use downed trees and logging "scraps" to fill in the rivers and create habitat that is crucial for the salmon. kinda ironic redoing what the undid in the 70's [confused]

Actually the DFW has gotten better at brush hogging Russian olive. I noticed recently they cleared the field at the top of Pompey mountain on Walpack WMA. A few years ago it was a Russian olive jungle.

The DWGNRA land does not get anything cleared up it has rampiant Russian Olive and Barberry.

The bear crap around my bait is loaded with those berrys. Russian Olives don't turn red.
That sounds like barberry. I have seen red tinted bear crap where there are a lot of barberry.

Bears also eat a lot of chokecherries when that is around. With that their crap is almost black with a lot of seeds.You see this a lot in Waywayanda.

laeagnus angustifolia is a usually thorny​ shrub or small tree growing to 5–7 m in height. Its stems, buds, and leaves have a dense covering of silvery to rusty scales. The leaves are alternate, lanceolate, 4–9 cm long and 1-2.5 cm broad, with a smooth margin. The highly aromatic flowers, produced in clusters of 1-3, are 1 cm long with a four-lobed creamy yellow calyx; they appear in early summer and are followed by clusters of fruit, a small cherry-like drupe 1-1.7 cm long, orange-red covered in silvery scales. The fruits are edible and sweet, though with a dryish, mealy texture. Its common name comes from its similarity in appearance to the olive (Olea europaea), in a different botanical family,
Both thorny and red berries
