ARC Energy Trust files its Annual Information Form

CALGARY, March 25 /CNW/ - (AET.UN and ARX - TSX) ARC Energy Trust (the
"Trust") today filed its Annual Information Form ("AIF") with the Canadian
securities regulatory authorities on SEDAR in Canada. The AIF includes the
Trust's reserve data and other oil and gas information for the year ended
December 31, 2007 as mandated by National Instrument 51-101 Standards of
Disclosure for Oil and Gas Activities of the Canadian Securities
Administrators. The Trust has also filed its Form 40-F, which includes the
annual information form, with the U.S. Securities and Exchange Commission on
EDGAR in the United States. Copies of the Trust's Annual Information Form may
be obtained on www.sedar.com or on the Trust's website at
www.arcenergytrust.com.

ARC Energy Trust is one of Canada's largest conventional oil and gas
royalty trusts with an enterprise value of approximately $6.3 billion. In
2008, the Trust expects to produce approximately 63,000 barrels of oil
equivalent per day from five core areas in western Canada. ARC Energy Trust
units trade on the TSX under the symbol AET.UN and ARC Resources exchangeable
shares trade under the symbol ARX.

Note: Barrels of oil equivalent (boe) may be misleading, particularly if
used in isolation. In accordance with NI 51-101, a boe conversion ratio for
natural gas of 6 mcf:1 bbl has been used, which is based on an energy
equivalency conversion method primarily applicable at the burner tip and does
not represent a value equivalency at the wellhead.

investors with information regarding ARC, including management's assessment of
ARC's future plans and operations, certain information contained in this

place undue reliance on forward-looking statements, as there can be no
assurance that the plans, intentions or expectations upon which they are based
will occur. By their nature, forward-looking statements involve numerous
assumptions, known and unknown risks and uncertainties, both general and
