Thank You so much, what I see our Acers don`t have tar spot so far, but our
vets was afraid for the toxicity off the tree.
But I heard many off the gardens used them even as fodder, but stopped because
off the tar spot and not for this?

We looked at this a few years ago Stephen, you’re absolutely right about the
seed casting issue as Ton also mentioned I think. The issue over the Tar Spot
was something that our vet team found if I remember right, I’d have to go back
through loads of emails to try and find out exactly what was said, which I’m
afraid I don’t have time for at present. If things ever quieten down, I’ll try
and find out.

Hi David, is this bloat a new issue with tar spot? I had in my head that the
issue with sycamore was the green seeds falling in high winds on poor pasture,
and the horses ate the seeds which have enough toxins to cause problems. The
tar spot had been thought an issue at first. Never heard of bloat before! But
then I'm a plant person not a vet......

Hi Ton et al,
we feed Acer pseudoplatanus regularly to the African Elephants at Howletts
EARLY in the season. However, a few years ago we made the decision that once
the season moves on and before ‘Tar Spot’ Rhytisma acerinum starts to develop
on the leaves we stop feeding as we found a link between this and bloat in
horses whilst investigating why some of the elephants seemed to be experiencing
the same. It is difficult to say for sure if this helped to resolve the
problem as we also made other changes to the diet at the same time but we have
not had a problem since.
Having said all of that there are Sycamore trees around one of the paddocks
which the animals have access to and of course the leaves fall into the paddock
at this time of year, but we have at least reduced the volume that they were
able to consume and perhaps this was enough to control the problem.
So, yes we feed it in the spring but not later in the year just in case the Tar
Spot was contributary to the bloating, but they do have limited access to Acer
pseudoplatanus and any tar spot that it may contain.
Best wishes,

Hi Ton,
We do not use them anylonger as browse for the elefants because of concernes
with toxicity. However when we did we did not have any problems.
Kind regards Søren

Emne: [ezg] acer platanoides in combination by Asian elephants
Dear all, we were planning to plant 3 big acer Acer pseudoplatanus by Asian
elephants to give them more shade.
This big trees are already standing in the parc and have to be moved to another
place.
I red that acer platanoides has concentrations of hypoglycin A what can course
atypical myopathy in horses.

Now I don’t know by Asian elephants and had any of you experience or opinion
of this?
Best regards, Ton
