We present a wide-field image of the Mon R2 star-forming region obtained with the Wide-Field Camera on UKIRT in the 2.12 µm filter centered on the H₂1-0 S(1) emission line. We report the discovery of 15 new H₂ jets in Mon R2 and 2 in L1646 and confirm most of these discoveries using archival Spitzer IRAC 4.5 and 8.0 µm images. We find that many of these protostellar jets are found in projection against the outflow cavities of the huge CO outflow in Mon R2, suggesting that the jets may be associated with an episode of star formation in Mon R2 triggered by this large, but now fossil, outflow. We also study the spatial distribution of small, localized reflection nebulae and find that these are distributed in the same way as photometrically identified Class I sources.
