Appellant, John Katkish, sued the District of Columbia for negligence for property damage caused by a tree that fell on his house. He appeals the decision of the Superior Court in favor of the District. Katkish contends on appeal that the trial court erred in not finding the District negligent and ruling that expert testimony was necessary to establish a standard of care. He also contends that the trial court erred in not drawing an adverse inference against the District because it omitted an employee with personal knowledge about the circumstances of the case from its witness list and failed to identify the employee in its response to appellant’s interrogatories. We affirm.
I. FACTUAL SUMMARY
1. The Trial
Appellant testified that on May 27, 1994, a large tree fеll on his house. Appellant had called the District of Columbia Tree and Landscape Division of the Department of Public Works on May 20, 1994 to complain about this tree because he noticed the tree had shifted and was leaning more prominently tоward his house. Appellant testified that he represented to the employee who took the call that this was an emergency situation and the sidewalk was cracked and uplifted. The Tree and Landscape Division’s record of the call, hоwever, shows the caller reporting a tree that is “dead” and “leaning.” The trial court found that appellant had not conveyed the emergency nature of the situation, noting that appellant did not call or write the District again after May 20, and thаt even though appellant saw a Tree and Land Division crew in front of his house a few days after his call, he did not approach them about the tree in front of his house.
Appellant called Mr. James Biller as an expert arborist. Mr. Biller testified that a sixty-foot oak tree leaning toward a house with a lifting curb would warrant immedi *705 ate inspection and possible abatement. The trial court rejected the opinion of Mr. Biller because he failed to define a national standard of care fоr the maintenance of leaning trees or the response time to notification of that condition. In addition, Mr. Biller based his opinion on what Virginia municipalities do and lacked familiarity with the District of Columbia’s horticultural situation and how it compared tо that in Virginia.
Appellant also called Mr. Thomas Mayer as an expert in utility arboriculture. Mr. Mayer’s testimony was rejected by the trial court because he did not specify a national standard or one relating to comparable municipalitiеs. The trial court observed that, “neither Mr. Mayer nor Mr. Biller presented any standard of care that related curb and street changes to a need for inspection and response.” The court also rejected the portions of Mr. Mayer’s and Mr. Billеr’s opinions based on hypothetical questions because they rested on the portions of testimony of Mr. Katkish, that the court did not accept, about the emergency nature of the situation.
2. Missing Witness Inference
On the first day of trial, Ms. Sandra Hill, a D.C. Department of Public Works еmployee, testified that Alvin Baltimore was the data entry clerk who apparently took the call from appellant on May 20. After the close of the evidence, appellant asked the trial court for an adverse inference аgainst the District, under the missing-witness presumption, because the District had offered no explanation as to why Alvin Baltimore, a current employee of the District, did not testify. The trial court questioned whether Mr. Baltimore was “peculiarly available” to the District and why appellant’s attorney did not attempt to contact Mr. Baltimore once his identity and current employment was established. The trial court did not draw an adverse inference from the District’s failure to call Mr. Baltimore as a witness.
II. ANALYSIS
1. Negligence
The trial cоurt held that appellant did not meet his burden of proof as to the negligence of the District of Columbia. We agree. Where the judgment of the trial judge as the trier of fact relied on an evaluation of a witness’s credibility, we will not disturb the findings unless they are “plаinly wrong or without evidence to support them.”
In re Button,
Based on the trial court’s finding that appellant did not convey the emergency nature of the situation, we agree with its ruling that expert testimony wаs necessary to establish the standard of care in this case. While expert testimony regarding the appropriate standard of care is not necessary for acts ‘“within the realm of common knowledge and everyday experience,’ ”
Messina v. District of Columbia,
In
Messina,
we held that whether the District should conform to a particular cushioning standard for the ground under the monkey bars on a school playground to prevent injuries required expert testimony.

2. Missing Witness Inference
Appellant secondly argues that the trial court erred in not drawing an advеrse inference because of the missing testimony of Mr. Alvin Baltimore, the data entry clerk who entered appellant’s May 20 call into the computer. In a jury trial, the trial court’s decision to permit such an argument or give an instruction is reviewed for abusе of discretion.
See Reyes-Contreras v. United States,
The requirements for a missing witness inference are that the party proposing such inference must demonstrate that the missing witness is, “(a) able to elucidate the transaction such that he might be expected to be called as a witness; and (b) is peculiarly available to the party against whom the inference (of unfavorable testimony) is made.”
Reyes-
*707
Contreras,
In this cаse, appellant did not demonstrate that the trial court abused its discretion in applying the law or erred as fact finder by declining to draw a missing witness inference. The trial court noted that appellant’s counsel made no attempt to depose Mr. Baltimore or to obtain his testimony after his name and role in entering appellant’s call were discussed on the first day of a four-day trial.

Under these circumstances, and given the principle that the missing witness inference “need not be appliеd broadly or rigidly,”

Affirmed.
Notes
. Appellant cites
Husovsky v. United States,
. Some courts have held that the "peculiarly available” requirement does nоt permit an inference to arise from the failure of one party to call a witness unless there is a showing that the witness was not available to be subpoenaed by the other party.
See Brown v. United States,
. Appellant argued during oral argument that the trial court errеd in stating that it "could not” draw an adverse inference because the witness was not peculiarly available. Appellant is incorrect. First, there is no statement in the record of the trial judge stating that he "could not” draw an adverse inference. Sеcond, had the trial judge stated that he "could not" draw an adverse inference if the witness was not peculiarly available, he would have been correct. An adverse inference is not permitted unless the two requirements from
Reyes-Contreras,
discussed in the text, are met.
