Forum rules and no-advertising policy

As a participant on this forum, it is your responsibility to know and follow our rules. Please read this message in its entirety.

Board Rules

1. You’re responsible for what you say.
As outlined in Section 230 of the Communications Decency Act, The Chronicle of the Horse and its affiliates, as well Jelsoft Enterprises Ltd., the developers of vBulletin, are not legally responsible for statements made in the forums.

This is a public forum viewed by a wide spectrum of people, so please be mindful of what you say and who might be reading it—details of personal disputes are likely better handled privately. While posters are legally responsible for their statements, the moderators may in their discretion remove or edit posts that violate these rules. Users have the ability to modify or delete their own messages after posting, but administrators generally will not delete posts, threads or accounts upon request.

Outright inflammatory, vulgar, harassing, malicious or otherwise inappropriate statements and criminal charges unsubstantiated by a reputable news source or legal documentation will not be tolerated and will be dealt with at the discretion of the moderators.

2. Conversations in horse-related forums should be horse-related.
The forums are a wonderful source of information and support for members of the horse community. While it’s understandably tempting to share information or search for input on other topics upon which members might have a similar level of knowledge, members must maintain the focus on horses.

3. Keep conversations productive, on topic and civil.
Discussion and disagreement are inevitable and encouraged; personal insults, diatribes and sniping comments are unproductive and unacceptable. Whether a subject is light-hearted or serious, keep posts focused on the current topic and of general interest to other participants of that thread. Utilize the private message feature or personal email where appropriate to address side topics or personal issues not related to the topic at large.

4. No advertising in the discussion forums.
Posts in the discussion forums directly or indirectly advertising horses, jobs, items or services for sale or wanted will be removed at the discretion of the moderators. Use of the private messaging feature or email addresses obtained through users’ profiles for unsolicited advertising is not permitted.

Company representatives may participate in discussions and answer questions about their products or services, or suggest their products on recent threads if they fulfill the criteria of a query. False "testimonials" provided by company affiliates posing as general consumers are not appropriate, and self-promotion of sales, ad campaigns, etc. through the discussion forums is not allowed.

Paid advertising is available on our classifieds site and through the purchase of banner ads. The tightly monitored Giveaways forum permits free listings of genuinely free horses and items available or wanted (on a limited basis). Items offered for trade are not allowed.

Advertising Policy Specifics
When in doubt of whether something you want to post constitutes advertising, please contact a moderator privately in advance for further clarification. Refer to the following points for general guidelines:

Horses – Only general discussion about the buying, leasing, selling and pricing of horses is permitted. If the post contains, or links to, the type of specific information typically found in a sales or wanted ad, and it’s related to a horse for sale, regardless of who’s selling it, it doesn’t belong in the discussion forums.

Stallions – Board members may ask for suggestions on breeding stallion recommendations. Stallion owners may reply to such queries by suggesting their own stallions, only if their horse fits the specific criteria of the original poster. Excessive promotion of a stallion by its owner or related parties is not permitted and will be addressed at the discretion of the moderators.

Services – Members may use the forums to ask for general recommendations of trainers, barns, shippers, farriers, etc., and other members may answer those requests by suggesting themselves or their company, if their services fulfill the specific criteria of the original post. Members may not solicit other members for business if it is not in response to a direct, genuine query.

Products – While members may ask for general opinions and suggestions on equipment, trailers, trucks, etc., they may not list the specific attributes for which they are in the market, as such posts serve as wanted ads.

Event Announcements – Members may post one notification of an upcoming event that may be of interest to fellow members, if the original poster does not benefit financially from the event. Such threads may not be “bumped” excessively. Premium members may post their own notices in the Event Announcements forum.

Charities/Rescues – Announcements for charitable or fundraising events can only be made for 501(c)(3) tax-exempt organizations. Special exceptions may be made, at the moderators’ discretion and direction, for board-related events or fundraising activities in extraordinary circumstances.

Occasional posts regarding horses available for adoption through IRS-registered horse rescue or placement programs are permitted in the appropriate forums, but these threads may be limited at the discretion of the moderators. Individuals may not advertise or make announcements for horses in need of rescue, placement or adoption unless the horse is available through a recognized rescue or placement agency or government-run entity or the thread fits the criteria for and is located in the Giveaways forum.

5. Do not post copyrighted photographs unless you have purchased that photo and have permission to do so.

6. Respect other members.
As members are often passionate about their beliefs and intentions can easily be misinterpreted in this type of environment, try to explore or resolve the inevitable disagreements that arise in the course of threads calmly and rationally.

If you see a post that you feel violates the rules of the board, please click the “alert” button (exclamation point inside of a triangle) in the bottom left corner of the post, which will alert ONLY the moderators to the post in question. They will then take whatever action, or no action, as deemed appropriate for the situation at their discretion. Do not air grievances regarding other posters or the moderators in the discussion forums.

Please be advised that adding another user to your “Ignore” list via your User Control Panel can be a useful tactic, which blocks posts and private messages by members whose commentary you’d rather avoid reading.

7. We have the right to reproduce statements made in the forums.
The Chronicle of the Horse may copy, quote, link to or otherwise reproduce posts, or portions of posts, in print or online for advertising or editorial purposes, if attributed to their original authors, and by posting in this forum, you hereby grant to The Chronicle of the Horse a perpetual, non-exclusive license under copyright and other rights, to do so.

8. We reserve the right to enforce and amend the rules.
The moderators may delete, edit, move or close any post or thread at any time, or refrain from doing any of the foregoing, in their discretion, and may suspend or revoke a user’s membership privileges at any time to maintain adherence to the rules and the general spirit of the forum. These rules may be amended at any time to address the current needs of the board.

Please see our full Terms of Service and Privacy Policy for more information.

Thanks for being a part of the COTH forums!

  • Maple Trees

    Are all Maple trees toxic to horses? Are some OK? If so, which ones. Thanks!

    No. So called Red Maple http://en.wikipedia.org/wiki/Acer_rubrum is the toxic one. At the bottom of this article it states that 1.5 pounds of leaves can cause illness-My vet has seen death in a horse with a MUCH smaller ingestion. She also says the leaves are not toxic until they begin to wilt and die. Scary.

      There have been studies on the Silver Maple as well- but inconclusive results (meaning I know about the study but can't find results of such study!).

      I've heard of a very low tolerance for Red Maple once leaves wilt.

        Actually, most of them are safe except for Acer Rubrum, the typical red maple. Our horse pastures have been lined for 10 years with full sized silver and sugar maples and they're fine. Fatten up in the fall from the leaves... but fine. I did just move and have Japanese maples which are physically red, but have yet to find out whether these are dangerous or not.

          We seem to have silver, and sensation maples.

            Cherry trees, at least wild cherry trees, have the same toxic properties when the leaves are wilting.

              It's actually a different toxic principle in cherry trees (and all members of the prunus species, including apricots, peaches and plums). When the leaves wilt, they release a cyanogenic glycoside called prunasin. When those reach the cecum/large intestine, they are converted to free cyanide and the animal dies of cyanide poisoning. The cyanide blocks the ability of hemoglobin to release oxygen so the animal's tissues basically become starved of oxygen. Because of the way horses digestive tracts are set up, they are less likely to be poisoned by wilted cherry leaves than ruminants such as cattle.

              In Red maples and hybrids of red maple (and possibly silver maples, as already mentioned), the toxin, which has not yet been identified, acts much differently. The toxin in red maple oxidizes hemoglobin in red blood cells causing formation of Heinz Bodies leading to hemolytic anemia. The scary thing with maple is that the leaves are toxic when wilted or dried, and in fact they've discovered that they appear to be more toxic as the leaves get older (i.e., more toxic in fall when dried leaves fall). Horses apparently also find them pretty tasty. Only takes about 6 pounds to kill a pony in as little as 1-5 days. Horses are the only known species to be affected by maple poisoning.

                Here's an excellent link from the Ontario Ministry of Agriculture.
                I'm in Ontario and goodness knows we have a LOT of maple trees


                It's only the dead, wilted, dried-up leaves of the read maple that are toxic.
                And 1.5 pounds of dried up leaves is a LOT of leaves.

                I have a red maple bordering my pasture and I have never, ever seen my horses show ANY interest in the leaves, dead or alive.

                  Ditto here.
                  Experience is what you get, when you didn't get what you wanted.
