• 4 plants (14 stems) found in 1998<br />
• new record for E. <strong>Ontario</strong>; significant disjunct for population (closest<br />
known population in Niagara area and in upper New York state<br />
• size and quality of marsh habitat must be maintained; potential<br />
threats include changes in water quality and level, and erosion<br />
through wave action<br />
• population should be monitored regularly<br />
• small band of several hundred plants along north shore of Outlet<br />
Creek near woodyard and dock; also along south shore near County<br />
Road 18 bridge<br />
• restricted to Great Lakes beaches and dunes<br />
• dominant ground cover with Sand Cherry on leeward sides of<br />
foredune and sections of back dunes at West Lake<br />
• reduced at Outlet dunes due to trampling and erosion, but<br />
rebounding due to protection – some planted from nursery<br />
• planted plots from Pinery stock are largest populations in park – no<br />
longer used in dune rehabilitation<br />
• nurseries of <strong>Sandbanks</strong> stock still maintained on one tilebed<br />
• unknown origin – possible accidental introduction<br />
• small patch of 50 stems along main path through West Lake bar on<br />
low dune ridge dominated by Little Bluestem<br />
• most easterly North American record; 390 km disjunct from other<br />
<strong>Ontario</strong> populations<br />
• genus is new record for Eastern <strong>Ontario</strong> – taxonomy of genus<br />
unclear, but most species rare in <strong>Ontario</strong><br />
• found in cedar graveyard on loose sand at West Lake dunes in a 30 x<br />
30 m area<br />
• growing with Seaside Spurge and Tall Wormwood<br />
• last seen in 1986 in back Outlet dunes<br />
• needs to be confirmed<br />
• occurs sporadically in foredunes and leeward base of back dunes at<br />
West Lake; one population found in Outlet sector<br />
• thousands of plants along 3 m wide strip at interface of wet panne<br />
and high isolated dune at West Lake<br />
• grows with Twig-rush and white-cedar seedlings<br />
• may be close to proposed dunes trail<br />
• found on active back dunes adjacent to West Lake, northwest of<br />
former pit<br />
10 This document uses the terminology and rankings proposed by the OMNR (June 2006). Species’ status<br />
assessments are made provincially by COSSARO (Committee on the Status of Species at Risk in <strong>Ontario</strong>).<br />
The provincial “S-ranks” are assigned by the OMNR’s Natural Heritage Information Centre (NHIC). S1 –<br />
extremely rare in <strong>Ontario</strong>; S2 – very rare in <strong>Ontario</strong>; S3 – rare to uncommon in <strong>Ontario</strong>.<br />
11 Datum is NAD27. UTMs are not available for all species, and some require verification.<br />
