I used our Terex P110 skid loader with a Fecon flail brush head to open up an old fire break that had not been touched for perhaps a decade.  Below is the photo before and then about 30 minutes after.  Now, if I did this work myself, by hand with a chainsaw, it would take me a few full days.  So brush mowers do quick work.   But follow up is important:  Next May I need to go to this fire break and spray the re-sprouting brush with our basal bark herbicide mix.   This would be when the honeysuckle re-sprouts are maybe a foot tall, showing off to me where they had been hiding under the mowing slash.  The oil based herbicide sprayed direct down on the sprouts is very effective at killing them.   The prescribed fire regime these breaks support will help to bring back this rare community of savanna and wet prairie.
