I’d rather do it with a template tag but I did realize that I can use the shortcode and do_shortcode to pull topics by forum on the forums index:

<?php echo do_shortcode('[bbp-single-forum id=$forum_id]') ?>

For those who are interested but not completely clear, a forum’s id can be found easily by viewing the source code in your browser and looking for the id or class of a forum listing’s containing element (for example: id=”bbp-forum-2536″ or class=”post-2536″).
