• 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 />
